Hand Gesture Engine

A modular, extensible hand gesture recognition engine built in Python using MediaPipe landmarks. Designed for real-time applications, clean architecture, and easy integration into games, apps, and AI projects. Perfect for:

• Computer Vision projects
• Gesture-controlled apps
• Games & UI interaction
• esearch & prototyping

Features

• Modular gesture detection system
• Real-time hand landmark processing
• Centralized gesture recognizer (brain logic)
• Configurable thresholds (pinch, thumb, etc.)
• Built-in logging (debug & production ready)
• CPU / GPU backend auto-selection
• Clean project structure
• YAML configuration support
• Confidence scoring
• Stable public API
• Ready for extension with custom gestures

Supported Gestrues

Installation

pip install mediapipe opencv-python

Then:

pip install hand-gesture-engine==0.1.1

Quick Start

Sample Code:

import cv2
from hand_gesture import GestureEngine, GestureConfig

config = GestureConfig.from_yaml("gesture_config.yaml")
engine = GestureEngine(config=config)

cap = cv2.VideoCapture(0)

while cap.isOpened():
    ret, frame = cap.read()
    if not ret:
        break

    frame, gesture = engine.process(frame)

    if gesture:
        print("Detected:", gesture)

    cv2.imshow("Gesture Engine", frame)
    if cv2.waitKey(1) == 27:
        break

Configuration

IMPORTANT:

Add/Create gesture_config.yaml in the same working directory:

backend: AUTO

stability:
  hold_time: 0.35
  min_confidence: 0.6

thresholds:
  pinch: 0.04
  thumb_extended: 0.25
  finger_tolerance: 0.05

GerstureEngine

engine = GestureEngine(
    backend="AUTO",  # AUTO | CPU | GPU
    config=config
)

Logging

Enable logging via config:

GestureConfig(enable_logging=True)

Logs include:

• Backend selection
• Detection failures
• Gesture recognition results

Future Ideas

Roadmap

• Gesture smoothing
• Multi-hand support
• Custom gesture training
• Mobile optimization
• ONNX / TensorRT backend
