CVChess is an computer vision system designed to recognize chess positions from images with a high level of accuracy. The project leverages deep learning and computer vision techniques to automatically detect and classify chess pieces and their positions on a chessboard, converting visual information into standard chess notation (FEN - Forsyth–Edwards Notation).
- Advanced chess piece recognition using deep learning
- Support for multiple viewing angles (multi-view approach)
- FEN string generation from chess position images
- Achieves 64% accuracy, which is 3 times better than previous state-of-the-art solutions
- Handles various lighting conditions and piece styles
- Integrated with standard chess notation and analysis tools
- Built using PyTorch for deep learning
- ResNet-18 based architecture for robust feature extraction
- Bayesian optimization for hyperparameter tuning
- Custom data processing pipeline for chess position analysis
- Supports both overhead and multi-view camera angles
- Efficient batch processing of chess position images
