Complete Iris Recognition Preprocessing Framework

Comprehensive preprocessing pipeline for iris recognition system, featuring modular functions for basic image enhancement, Canny edge detection, Hough transform-based circular boundary localization (inner and outer iris boundaries), and final normalization converting circular iris rings to rectangular formats. Includes sample images and custom GUI interface - while requiring further refinement, the core preprocessing tasks are effectively implemented. Performance optimization suggestions include replacing Hough transform with least-squares fitting algorithm for improved boundary detection accuracy.
