Detailed Documentation
This MATLAB program implements segmentation and recognition of digits and Chinese characters from second-generation ID cards. The solution features a custom-designed graphical user interface (GUI) with robust performance. Key technical approaches include connected component analysis for character segmentation and template matching algorithms for recognition. The implementation involves preprocessing steps like binarization and morphological operations before applying regionprops() function for connected component extraction. For recognition, normalized cross-correlation compares segmented characters with pre-built templates. The accompanying folder contains a research paper detailing the algorithmic methodology, which proved instrumental in development. The system achieves over 80% accuracy in combined segmentation and recognition tasks, demonstrating reliable performance for ID card information extraction.
