Detailed Documentation

This MATLAB code provides a comprehensive solution for calculating precision and recall metrics in image annotation systems. The implementation includes functions to process annotation results, compare predicted labels with ground truth data, and compute evaluation metrics using confusion matrix analysis. Key features include automated true positive/false positive detection, statistical calculation of precision (TP/(TP+FP)) and recall (TP/(TP+FN)), and visualization tools for performance analysis. The code enables quantitative assessment of annotation algorithm performance, helping developers identify areas for improvement in both accuracy and completeness. By analyzing precision-recall trade-offs, users can optimize threshold settings and enhance algorithm reliability for practical applications. The modular design allows easy integration with existing image processing pipelines and supports batch processing for large-scale annotation evaluation.
