iriscodes
Iriscodes, or IrisCodes, are binary representations of iris texture used in biometric identification. They encode distinctive patterns in the human iris into compact bit strings that allow fast numeric comparison. The concept was popularized by John Daugman in the 1990s as part of iris recognition research and has since become a standard in many biometric systems.
Generation of an iricode involves several steps. First, the iris region is located and segmented to separate
Matching between two iriscodes is performed with the Hamming distance, typically computed only over the overlapping,
Limitations include dependence on high-quality iris images and accurate segmentation; occlusions, reflections, or off-angle captures can
