# Thai License Plate Detection App 🚗

This Streamlit application detects and recognizes Thai license plates and provinces from images. It uses YOLOv8 for object detection and TrOCR for text recognition.

## Features

- 📷 Upload images containing Thai license plates
- 🔍 Detect and extract license plate numbers
- 🏠 Recognize and match province names
- 🖼️ Display cropped regions of detected plates and provinces
- 🎯 High accuracy text recognition using TrOCR

## How to Use

1. Upload an image containing a Thai license plate using the file uploader
2. Wait for the processing to complete
3. View the results:
   - Detected license plate number
   - Cropped license plate image
   - Detected province name
   - Cropped province image

## Technical Details

The application uses:
- YOLOv8 for license plate and province detection
- TrOCR (Thai) for text recognition
- OpenCV for image preprocessing
- Levenshtein distance for province name matching

## Models

- Object Detection: YOLOv11 (custom trained for Thai license plates)
- Text Recognition: openthaigpt/thai-trocr
