This paper described a rapid and accurate iris recognition method.Firstly,got the location and size of the iris through the image preprocessing,and then unwrap the localized iris to a rectangular texture block with a fixed size.Secondly,detected all of the feature points on each scan lines in the image utilizing the method of finding local gray minimum points,and then abandoned the false feature points and got a fixed length iris code.Thirdly,calculated the Hamming distance between two iris codes and then obtained the recognition result according to the Hamming distance.
