How the System Works

The AutoAttendance system operates in three main phases:

Phase 1: Data Collection

Operator starts the data collection mode
System captures 80-100 face samples of a person from various angles
Samples are automatically saved to the database

Phase 2: Model Training (Registration)

System loads all collected face samples
InsightFace deep learning model converts each face into a numeric vector (embedding)
Embeddings are stored in SQLite database
Note: The deep model is pre-trained; this phase registers new people into the system

Phase 3: Live Recognition

Camera feed is processed in real-time
System detects faces in each frame
For each detected face:
- Generates an embedding using InsightFace
- Compares against all stored embeddings using cosine distance
- If distance ≤ threshold → Known Person (attendance marked)
- If distance > threshold → Unknown Person (alert sent)
Anti-spoofing check verifies face is real (not photo/screen)
Attendance is automatically recorded in database

Why This Approach Works

Traditional face recognition systems train a classifier from scratch, requiring thousands of labeled examples. AutoAttendance uses embedding-based recognition, where:

A pre-trained deep model extracts face features
Similar faces produce similar embeddings
Simple distance metrics (cosine distance) determine matches
New people can be added with just 80-100 samples
System is fast, scalable, and requires minimal training data

Tuning Parameters

RECOGNITION_THRESHOLD

0.30-0.40: Very strict (fewer false accepts, more false rejects)
0.40-0.50: Balanced (recommended)
0.50-0.60: Lenient (more false accepts)

When to adjust:

Too many unknowns → Lower threshold (0.40)
Too many false recognitions → Raise threshold (0.50)

CAMERA_ID

If camera doesn't work:

Windows: Try 0, 1, 2, 3
Linux: Check /dev/video*
Mac: Usually 0

FRAME_PROCESS_INTERVAL

Lower (2-3): Faster recognition, higher CPU
Higher (8-10): Lower CPU, slower response

Troubleshooting

Issue: Camera Not Found

Solution:

# Edit config.py
CAMERA_ID = 1  # Try different numbers

Windows - Using Device Manager:

Open Device Manager
Find camera under "Imaging devices"
Right-click → Properties → Note the Device ID
Try camera IDs: 0, 1, 2, 3

Issue: Poor Recognition Accuracy

Causes & Solutions:

Not Enough Training Samples
- Collect at least 100 samples per person
- Vary angles, lighting, distances
Threshold Too High
- Lower RECOGNITION_THRESHOLD to 0.40
Poor Lighting
- Improve camera lighting
- Use natural light when possible
Spoofed Face Detected
- User must present real face
- Increase SPOOF_THRESHOLD slightly

Issue: System Runs Slowly

Causes & Solutions:

Too Many Frames Being Processed
- Increase FRAME_PROCESS_INTERVAL to 8-10
High Resolution
- Reduce FRAME_WIDTH and FRAME_HEIGHT to 480p
Multiple Faces in Frame
- Set INSIGHTFACE_MAX_FACES = 1
- Ensure only one person at camera
Insufficient RAM
- Close other applications
- Upgrade system RAM if possible

Issue: Unknown Emails Not Sending

Check:

Email address is valid
Gmail 2FA is enabled
App-specific password is set correctly
Internet connection is working

Test Email:

python -c "from email_notification import EmailNotification; EmailNotification().send_test_email()"

Issue: Database Corruption

Solution:

# Backup current database
copy models/attendance.sqlite3 models/attendance.sqlite3.backup

# Delete corrupted database
del models/attendance.sqlite3

# Retrain model
python cli.py train

AutoAttendance Project Architecture

1. Purpose

AutoAttendance is a face-recognition attendance system with two operating modes:

a desktop real-time attendance application that uses a webcam to recognize people and mark them present
a lightweight web dashboard and API that show attendance and registration data from the same database

The project is designed for day-to-day use by an operator, while also being structured clearly enough for academic review, prototyping, and further research.

2. What The System Does

At a high level, the system:

collects face images for each person
converts those images into face embeddings using a pretrained InsightFace model
stores the embeddings in SQLite
runs live recognition from a webcam
checks whether the detected face looks real or spoofed
records attendance for known people
exposes attendance data through exported files and a web dashboard

3. High-Level Architecture

4. Core Design Idea

This project is built around embedding-based face recognition.

That means the system does not train a face classifier from scratch. Instead, it uses a pretrained deep model to convert each face into a numeric vector called an embedding. During recognition, the system compares a new face embedding against the stored embeddings of registered people and finds the closest match.

This is the most important architectural idea in the project.

5. Main Subsystems

5.1 Configuration Layer

File: config.py

This file centralizes runtime settings such as:

camera device and frame size
processing interval for recognition
InsightFace model configuration
recognition threshold
database and data directory paths
anti-spoofing threshold

Important active settings:

INSIGHTFACE_MODEL_NAME = 'buffalo_l'
INSIGHTFACE_PROVIDERS = ['CPUExecutionProvider']
RECOGNITION_THRESHOLD = 0.45
DATABASE_PATH = 'models/attendance.sqlite3'
FRAME_PROCESS_INTERVAL = 5

Architecturally, this file acts as the control panel for the entire system.

5.2 Data Collection Subsystem

File: data_collection.py

Purpose:

collect face samples from the webcam
save them under data/faces/<person_name>/
guide the operator to capture different face angles

How it works:

the operator enters one or more names
the camera opens
the operator presses c to capture face samples
cropped face images are stored in that person's folder

This stage is the enrollment input stage of the system.

5.3 Registration / Training Subsystem

File: train_model.py

Purpose:

process collected face images
extract embeddings using InsightFace
save the embeddings into SQLite

Important note:

This stage is called "training" in the script name, but in the current architecture it is closer to registration than full model training. The deep model itself is pretrained. What changes over time is the set of stored person embeddings.

5.4 Recognition Engine

File: face_recognition.py

This is the core machine-learning module.

Responsibilities:

load the pretrained InsightFace FaceAnalysis app
detect faces in incoming frames
produce normalized face embeddings
compare each new embedding with stored embeddings
classify the face as known or unknown based on cosine distance

Recognition logic:

detect faces in the frame
compute an embedding for each face
compare the embedding with all stored embeddings
choose the best match by highest cosine similarity
convert similarity to distance using 1 - similarity
accept the match only if distance is below the configured threshold

So the recognition path is:

frame -> face detection -> embedding -> similarity search -> threshold decision

5.5 Anti-Spoofing Subsystem

File: anti_spoofing.py

Purpose:

reduce false acceptance from printed photos or screen displays

Current method:

Laplacian texture variance
grayscale contrast
high-frequency energy
color variation

These features are combined into a liveness score. If the score is above SPOOF_THRESHOLD, the face is treated as real.

Research note:

This is a heuristic passive liveness module, not a learned anti-spoofing network. It is useful as a lightweight safety layer, but it should not be treated as a state-of-the-art spoof defense.

5.6 Live Attendance Runtime

File: main.py

Purpose:

run the webcam-driven attendance workflow in real time

Responsibilities:

initialize the camera
load registered embeddings
process frames continuously
run recognition every FRAME_PROCESS_INTERVAL frames
run liveness checks on face crops
mark attendance for known faces
show results visually in the camera window
play alerts for unknown or spoofed detections
export the final report when the session ends

This is the primary operational application of the project.

5.7 Attendance Management Subsystem

File: attendance_manager.py

Purpose:

maintain daily attendance state
prevent duplicate attendance entries
write records to SQLite
generate operator-friendly output files

Outputs:

attendance.log
data/attendance/attendance.xlsx
data/attendance/attendance_YYYY-MM-DD.csv

This module acts as the bridge between recognition events and administrative reporting.

5.8 Data Persistence Subsystem

File: database.py

Purpose:

provide SQLite-backed storage for the whole system

Main tables:

students
face_embeddings
attendance
alerts

This database is the single source of truth used by both the desktop application and the web API.

5.9 Dashboard and API Subsystem

File: api.py

Purpose:

expose current attendance information through a FastAPI application
provide a built-in dashboard page

Endpoints:

/ : HTML dashboard
/api/summary : summary counts
/api/students : student records
/api/attendance : attendance records
/api/alerts : alert records

This subsystem is read-oriented. It visualizes and serves the data already generated by the desktop runtime and registration pipeline.

6. End-To-End Operational Workflow

Stage 1: Setup

Script:

python setup.py

What it does:

checks dependencies
creates required directories
prepares .env
tests the camera

Stage 2: Collect Face Samples

Script:

python data_collection.py

Output:

multiple cropped face images per person
stored under data/faces/<person_name>/

Stage 3: Register Embeddings

Script:

python train_model.py

Output:

people inserted or updated in SQLite
embeddings stored in models/attendance.sqlite3

Stage 4: Run Real-Time Attendance

Script:

python main.py

Runtime behavior:

webcam starts
faces are detected
known faces are matched and marked present
unknown faces trigger visual and audio alerts
spoof-like faces are rejected

Stage 5: View Results

Desktop outputs:

Excel file
CSV daily export
text log

Web dashboard:

uvicorn api:app --reload

Open:

http://127.0.0.1:8000

7. Detailed Runtime Data Flow

7.1 Enrollment Data Flow

Operator
  -> data_collection.py
  -> webcam frame
  -> detected face crop
  -> saved image file
  -> data/faces/<person_name>/

7.2 Registration Data Flow

Saved face images
  -> face_recognition.py
  -> InsightFace embedding extraction
  -> AttendanceDatabase.upsert_student()
  -> AttendanceDatabase.add_embedding()
  -> models/attendance.sqlite3

7.3 Attendance Data Flow

Live camera frame
  -> main.py
  -> face_recognition.recognize_frame()
  -> best embedding match
  -> anti_spoofing.is_liveness_detected()
  -> attendance_manager.mark_attendance()
  -> database attendance table
  -> Excel / CSV / log output

7.4 Dashboard Data Flow

SQLite database
  -> AttendanceDatabase queries
  -> FastAPI endpoints
  -> HTML dashboard and JSON API

8. Database Architecture

The database file is:

models/attendance.sqlite3

8.1 students

Stores identity-level information.

Typical fields:

id
name
external_id
department
email
phone
status
created_at

8.2 face_embeddings

Stores one or more embeddings for each student.

Typical fields:

id
student_id
embedding
embedding_dim
image_path
model_name
quality_score
created_at

This design allows multiple face samples per student, which is useful for better recognition robustness across pose and lighting changes.

8.3 attendance

Stores daily attendance events.

Typical fields:

id
student_id
student_name
date
time
status
confidence
camera_id
created_at

The current schema enforces:

UNIQUE(student_name, date)

So one person is recorded at most once per day.

8.4 alerts

Stores security or anomaly alerts.

Typical fields:

id
alert_type
message
image_path
created_at

Reportformat/ contains report-writing assets and is separate from the runtime system

10. File Responsibility Map

Runtime-critical files

main.py - real-time attendance loop
face_recognition.py - detection, embeddings, matching
anti_spoofing.py - liveness heuristics
attendance_manager.py - record management and exports
database.py - persistence layer
config.py - global settings

Enrollment and preparation files

data_collection.py - collect face images
train_model.py - register embeddings
setup.py - environment bootstrap

Monitoring files

api.py - web dashboard and JSON API

Optional or legacy-adjacent files

face_detection.py - Haar-cascade helper module, not the main active recognition path
email_notification.py - email utility module, currently not wired into the main runtime flow

11. User View Of The System

A normal operator can understand the project in four steps:

collect face samples for each person
register those people into the system
run the camera-based attendance app
view attendance in reports or the dashboard

From a user perspective, the desktop app is the main tool and the dashboard is the reporting interface.

12. Researcher View Of The System

A researcher should understand the project through these architectural properties:

the system uses a pretrained deep face model rather than training a new classifier
recognition is embedding-based and threshold-driven
the database stores multiple embeddings per identity
attendance is event-based and deduplicated per day
anti-spoofing is heuristic, lightweight, and passive
the dashboard is a thin read layer over operational data

This makes the system suitable for:

applied computer vision coursework
prototyping attendance automation
studying threshold-based recognition behavior
extending toward stronger liveness detection or multi-camera deployments

13. Strengths Of The Current Architecture

simple end-to-end workflow
clear separation between capture, recognition, storage, and presentation
one shared database for both the desktop app and web dashboard
multiple embeddings per person for stronger matching robustness
easy to extend because modules are already separated by responsibility

14. Current Limitations

These limitations are important for both users and researchers:

anti-spoofing is heuristic and not highly robust against advanced attacks
matching currently appears to use a linear scan over stored embeddings, which is fine for small deployments but not ideal at large scale
some older documentation still describes an LBPH/Haar-centered design, while the live code now uses InsightFace plus SQLite
RECOGNITION_MODEL_PATH = 'models/face_recognizer.yml' remains in configuration even though the active recognition path is database-based
email notification utilities exist but are not integrated into the live attendance workflow

15. Conceptual Architecture Summary

In one sentence:

AutoAttendance is an embedding-based face-recognition attendance platform in which enrollment images are converted into stored face embeddings, live camera frames are matched against those embeddings, attendance is written into SQLite, and results are exposed through exported reports and a FastAPI dashboard.

16. Minimal Architecture Summary For Presentation

If you need a short explanation for a user, teacher, or report:

The system first collects face images for each student, then converts those
images into numerical face embeddings using a pretrained InsightFace model.
During live attendance, each webcam frame is analyzed, matched against the
stored embeddings, checked for basic liveness, and then recorded in a SQLite
database. The same database powers exported attendance reports and a web
dashboard.

17. Suggested Future Improvements

replace heuristic anti-spoofing with a learned liveness model
store unknown-face snapshots in data/unknown_faces/
integrate alerts table writes directly from the live runtime
connect email_notification.py into attendance and alert events
add student metadata management through API endpoints
support multi-camera deployments
add ANN or vector indexing if the number of registered people grows large

18. Important Reality Check

Some files in the repository still reflect an older architecture based on LBPH and Haar cascades. The current live code path is different:

main recognition is handled by face_recognition.py using InsightFace
long-term storage is handled by SQLite in models/attendance.sqlite3
the dashboard reads from the same SQLite store

So this document describes the actual active architecture in code, not just the original intended design.

📊 How It Works

Three-Phase System

1️⃣ Data Collection

Collect 80-100 face samples per person
Various angles and lighting conditions
Automatic storage in SQLite

2️⃣ Model Training

InsightFace converts faces → embeddings
Embeddings stored in database
Model is pre-trained (no retraining needed)

3️⃣ Live Recognition

Real-time face detection
Embedding comparison (cosine distance)
Anti-spoofing verification
Automatic attendance marking

Why It's Effective

✅ Pre-trained model = No deep learning required
✅ Embedding-based = Minimal training data needed
✅ Cosine distance = Fast and accurate matching
✅ Scalable = Add new people anytime

Face Detection Not Working - Troubleshooting Guide

Quick Fix Checklist

Step 1: Train Face Embeddings (CRITICAL)

If you haven't done this yet, faces won't be recognized. Run:

python train_model.py

Expected output:

Processing karim: 100 images
  karim: 100/100 images registered
Processing masud: 50 images
Processing rudo: 40 images
Processing soumitra: 60 images
Registration completed successfully!
Total people registered: 4
Total embeddings registered: 250

Step 2: Restart the Web UI

After training, restart the web UI:

python run_web_ui.py

Step 3: Check Dashboard

Open http://localhost:5000
Check if "Face Embeddings" count shows > 0
If it shows 0, embeddings didn't load properly

Step 4: Test Face Detection

Click "Start Attendance" button:

Camera should open
Green box = Known person (attendance marked)
Red box = Unknown person (not in database)
Orange box = Spoofing detected (printed photo or screen)
No boxes = No faces detected (see troubleshooting below)

Troubleshooting If Faces Still Not Detected

Issue 1: No Face Boxes Appear at All

Possible Causes:

Camera Problem
- Is camera facing you?
- Is there enough light?
- Try moving closer to camera (30-60cm away)
InsightFace Model Not Loaded
- Check logs: logs/attendance_*.log
- Look for errors mentioning InsightFace or ONNX

Embeddings Not Trained

Check if database has embeddings:

python -c "from database import AttendanceDatabase; db = AttendanceDatabase(); print(f'Embeddings: {db.get_total_embeddings()}')"

If shows 0, run python train_model.py

Issue 2: Faces Detected But Not Recognized (Always "Unknown")

Possible Causes:

Training Images Are Poor Quality
- Use images with:
  - Clear, frontal face view
  - Good lighting
  - Neutral expression
- Remove blurry or side-view images
Recognition Threshold Too Strict
- Edit config.py:
```
RECOGNITION_THRESHOLD = 0.50  # Increase from 0.45 for more lenient matching
```
- Restart web UI
- Run python train_model.py again
Not Enough Training Images
- Retrain with more images (100+ per person recommended)
- Delete models/attendance.sqlite3
- Run python train_model.py

Issue 3: Model Loading Errors

Check Debug Output:

Open new terminal and run:

python -c "from face_recognition import FaceRecognitionModule; r = FaceRecognitionModule(); r.load_model()"

Look for errors about:
- InsightFace import failures → Install: pip install insightface onnx onnxruntime
- Model download failures → Check internet connection
- ONNX runtime errors → Install correct version: pip install onnxruntime

Key Components

1. Training Pipeline

Raw Images (data/faces/person_name/*.jpg)
    ↓
InsightFace Detector (detects face in image)
    ↓
Face Embedding (512-dimensional vector)
    ↓
SQLite Database (models/attendance.sqlite3)

2. Recognition Pipeline (Real-time)

Camera Frame
    ↓
InsightFace Detector (detects faces in frame)
    ↓
Face Embedding for each detected face
    ↓
Compare with Database Embeddings
    ↓
Display Result (Green/Red/Orange box)

3. Anti-Spoofing Check

Analyzes texture (Difference of Gaussians method)
Detects printed photos and screen replays
Must pass before attendance is marked

Verify Everything Works

Run this Python script to diagnose:

from database import AttendanceDatabase
from face_recognition import FaceRecognitionModule
import cv2

# Check embeddings
db = AttendanceDatabase()
embeddings = db.get_total_embeddings()
print(f"✓ Database embeddings: {embeddings}")

# Check model
rec = FaceRecognitionModule()
rec.load_model()
print(f"✓ Model loaded, known faces: {rec.label_count}")

# Check camera
cap = cv2.VideoCapture(0)
ret, frame = cap.read()
if ret:
    faces = rec.detect_faces(frame)
    print(f"✓ Camera works, detected {len(faces)} faces")
cap.release()

Still Having Issues?

Check logs:
```
tail -50 logs/attendance_202605.log
```
Look for these error patterns:
- "No face embeddings found" → Run python train_model.py
- "Failed to load model" → Check InsightFace installation
- "Cannot open camera" → Check CAMERA_ID in config.py
- "Error processing frame" → Check anti_spoofing module
Common fixes:
- Delete models/attendance.sqlite3 and retrain
- Update InsightFace: pip install --upgrade insightface
- Verify camera ID: Check System Information for correct device

How It Should Look

When working correctly:

✓ Dashboard shows count of registered faces
✓ Camera feed displays in real-time
✓ Faces show colored boxes (green = known, red = unknown)
✓ Names appear above faces
✓ Attendance records update in real-time

Detailed Compilation Explanation

What Happens When You Run pdflatex

First run:

pdflatex main.tex
↓
Reads main.tex
↓
Processes \include and \input commands
↓
Reads all chapter files
↓
Builds Table of Contents (stored in .toc file)
↓
Generates main.pdf (with ??? for TOC page numbers)

Second run:

pdflatex main.tex
↓
Uses .toc file from first run
↓
Generates correct page numbers in TOC
↓
Generates final main.pdf

This is why you need to run pdflatex twice!

Troubleshooting by Error Message

Error: "command not found: pdflatex"

Cause: LaTeX not installed or not in PATH Solution:

Install appropriate LaTeX distribution (see above)
Restart terminal/command prompt after installation

Error: "File 'chapter1.tex' not found"

Cause: Running pdflatex from wrong directory Solution:

Ensure you're in the AutoAttendance directory
Check file names match exactly (case-sensitive on Linux/Mac)

Error: "Undefined control sequence"

Cause: Missing LaTeX package or typo Solution:

Run pdflatex again (may auto-install on MiKTeX)
Check for typos in main.tex or chapter files

Warning: "Underfull hbox"

Cause: Text fitting issues (usually harmless) Solution: Usually safe to ignore, or adjust text

Compilation Takes Very Long

Cause: First run with MiKTeX downloading packages Solution: This is normal; subsequent runs are faster

Performance Tips

Fast Compilation

Use -interaction=nonstopmode flag:

pdflatex -interaction=nonstopmode main.tex

Clean temporary files before compiling:

rm -f *.aux *.log *.out *.toc  # Linux/Mac
del *.aux *.log *.out *.toc    # Windows

Skip viewing PDF during compilation

Faster Development Workflow

Comment out non-essential chapters in main.tex during editing
Use \documentclass[draft]{book} for draft mode
Disable TOC generation during editing

Verification Checklist

After successful compilation, check:

main.pdf file exists
PDF file size > 500KB
PDF opens in reader without errors
Title page displays correctly
Table of Contents has page numbers
All chapters are included
Equations render correctly
Tables display properly

Next Steps

Choose your preferred method from above
Follow the installation instructions for your OS
Navigate to project directory
Run compilation command twice
Open and verify main.pdf

AutoAttendance Presentation Slides

This Markdown file is a 15-slide presentation outline for the AutoAttendance project. It is based on the current codebase, the project report, and the active implementation in the repository.

Slide 1. Title Slide

Project title: AutoAttendance
Subtitle: Real-Time Face Recognition Based Automated Attendance System with Passive Liveness Detection
Presenter: Md. Mahfujul Karim Sheikh
Course: CSE 4206, Neural Network Lab
Institution: Northern University of Business and Technology Khulna

Slide 2. Problem Statement

Manual attendance takes time and interrupts class or work.
Paper registers and roll calls are prone to proxy attendance and recording errors.
A better system should be contactless, fast, and easier to manage.
AutoAttendance addresses these issues using webcam-based face recognition.

Slide 3. Project Goal

Capture and register face data for each person.
Recognize known faces from a live camera stream.
Mark attendance automatically and prevent duplicates.
Store data locally and expose it through a dashboard.
Add a lightweight liveness check to reduce spoofing.

Slide 4. System Overview

The project has two main runtime parts.
Desktop app: main.py for live camera attendance.
Web app: api.py for dashboard and summary data.
Database: models/attendance.sqlite3 stores students, embeddings, attendance, and alerts.

Slide 5. Project Architecture

data_collection.py collects face samples from the webcam.
train_model.py registers embeddings from collected images.
face_recognition.py performs detection and matching.
anti_spoofing.py checks passive liveness.
attendance_manager.py writes attendance to SQLite, Excel, CSV, and logs.

Slide 6. Technology Stack

Python is the main language.
OpenCV handles camera input and display.
InsightFace provides pretrained face analysis and embeddings.
SQLite stores all persistent data locally.
FastAPI powers the lightweight dashboard and API.
Pandas and OpenPyXL support reporting exports.

Slide 7. Face Data Collection

The operator enters one or more person names.
The webcam opens and face images are captured manually.
The script recommends varied angles and lighting for better recognition.
Images are saved under data/faces/<person_name>/.
The default collection target is 80 samples per person.

Slide 8. Registration and Model Setup

train_model.py does not train a new deep model from scratch.
It registers embeddings extracted from collected face images.
Each person is inserted or updated in SQLite.
The project uses a pretrained InsightFace model named buffalo_l.
This makes enrollment faster than retraining a classic LBPH model.

Slide 9. Recognition Workflow

A frame is captured from the webcam.
InsightFace detects faces and extracts normalized embeddings.
The embedding is compared with stored embeddings in SQLite.
Matching uses cosine similarity converted to cosine distance.
The configured recognition threshold is 0.45.

Slide 10. Attendance Logic

Known faces are marked present automatically.
Attendance is stored only once per person per day.
Duplicate prevention is enforced both in memory and in SQLite.
The system writes to attendance.log and data/attendance/attendance.xlsx.
A CSV daily report can also be exported.

Slide 11. Anti-Spoofing

The project uses passive liveness detection.
It checks texture variance, contrast, frequency energy, and color variation.
A weighted score determines whether a face looks real.
The liveness threshold is 0.35.
This helps block simple printed-photo or screen-based spoofing.

Slide 12. Web Dashboard and API

api.py serves a dashboard in the browser.
It shows total students, total embeddings, and present count for today.
It lists recent attendance records with confidence values.
It includes API endpoints for summary, students, attendance, and alerts.
The dashboard uses a clean, responsive HTML interface.

Slide 13. Data and Outputs

Registered students are stored in the students table.
Face embeddings are stored in the face_embeddings table.
Attendance events are stored in the attendance table.
Security and unknown-face events are stored in the alerts table.
Main outputs include SQLite data, Excel files, CSV reports, and logs.

Slide 14. Current Project Status

The repository contains a complete working prototype.
The report documents two enrolled people: karim and soumitra.
The project report also documents 200 stored face embeddings.
Example attendance data already exists in data/attendance/.
The system runs on CPU using CPUExecutionProvider.

Slide 15. Conclusion and Future Work

AutoAttendance shows a practical end-to-end attendance workflow.
It combines recognition, liveness checking, storage, and reporting.
The most useful future improvements are stronger liveness detection, multi-face support, authentication for the dashboard, and encrypted biometric storage.
The project is a solid base for a real deployment or further research.
