Iris Signature
After extracting the iris from the eye photo and representing it in a polar form
we can describe its feature set with a unique signature.
The image is decomposed during a 4-stage procedure and as an output we get the iris code having 3 possible states: -1, 0 and 1. We can represent it as an array of white, gray and black pixels.
After extracting the signature for a pair of eye pictures we can compare them and determine wheather they belong to the same person. The decision if the iris codes match or not is based on the certain value of hamming distance - details.
