Also percentage of correctly matched template has been found 87.5%. The segmentation time of algorithm is far better and can be used in real time applications for iris recognition. VI. C ONCLUSION We propose a new iris recognition method for the iris images degraded by noisy factors. The iris has been detected by color information of iris. And the iris authentication is completed by comparing the iris binary code based on “texture information” of iris region. As the experimental results, the matched efficiency has come out 87.5% and iris has been correctly detected in each test. In future works, work can be done for irises having different colors as our algorithm is suitable only for black or brown iris intensity levels. REFERENCES [1] A. Basit, M.Y.
