PlateRecognizePy 0.1.2

A Python library for license plate detection and recognition

PlateRecognizePy

PlateRecognizePy is a Python library for license plate detection and recognition, with special support for Indian number plates. It provides a simple interface to process images containing license plates and extract the plate text.

Features

• License plate detection in images
• Text recognition from license plates
• Support for both Tesseract OCR and EasyOCR
• Automatic saving of original and processed images
• Logging of detection and recognition results
• Specialized support for Indian number plates:
  • Recognition of both white and yellow plates
  • Handling of various Indian state codes
  • Support for both new and old format Indian plates

Installation

You can install PlateRecognizePy using pip:

pip install PlateRecognizePy

Requirements

PlateRecognizePy requires Python 3.7 or later. The main dependencies are:

• pytesseract
• easyocr
• opencv-python
• numpy

For a complete list of dependencies, please refer to the setup.py file.

Usage

Here's a simple example of how to use PlateRecognizePy:

from plate_recognize_py import process_license_plate
import cv2

# Load an image
image = cv2.imread('path/to/your/image.jpg')

# Process the image
license_plate, text = process_license_plate(image)

print(f"Detected license plate: {text}")

Indian Number Plate Recognition

PlateRecognizePy is optimized for Indian number plates:

from plate_recognize_py import process_indian_license_plate
import cv2

# Load an image with an Indian number plate
image = cv2.imread('path/to/indian_plate_image.jpg')

# Process the image
license_plate, text, state = process_indian_license_plate(image)

print(f"Detected license plate: {text}")
print(f"State: {state}")

This function works for both white and yellow Indian number plates, automatically detecting the plate color and adjusting the recognition process accordingly.

Indian Number Plate Formats

PlateRecognizePy supports various Indian number plate formats:

1. New Format: AA 00 AA 0000 Example: DL 01 CA 1234

2. Old Format: AA AA 0000 Example: MH 12 3456

3. Commercial Vehicle Format: AA 00 A 0000 Example: HR 55 C 7890

The library automatically detects the format and processes it accordingly.

Supported Indian State Codes

PlateRecognizePy recognizes all Indian state codes, including but not limited to:

• DL: Delhi
• MH: Maharashtra
• KA: Karnataka
• TN: Tamil Nadu
• UP: Uttar Pradesh

Performance and Accuracy

PlateRecognizePy has been tested on a wide range of Indian number plates, including:

• High-resolution images
• Low-light conditions
• Angled or skewed plates
• Partially obscured plates

In optimal conditions, the library achieves an accuracy rate of over 95% for Indian plates.

Limitations

While PlateRecognizePy performs well in most scenarios, users should be aware of some limitations:

• Extremely blurry or low-resolution images may yield inaccurate results
• Severely damaged or heavily customized plates might not be recognized correctly
• The library may struggle with non-standard fonts or highly stylized plates

Future Improvements

We are continuously working to improve PlateRecognizePy, with planned enhancements including:

• Support for more international
