A Kind of Identification Technology Based on Iris Recognition
WU An-xiong · Microcomputer Information · 2010
Iris recognition which is a bio-identification method is emerging in recent years,iris recognition algorithm is gradually being applied to many important areas by its simple,rapid identification and lower error recognition rate. Daugman algorithms by analyzing the limitations of existing proposed a new improved iris recognition algorithm,which combines integral-differential operator and Hough transform to carry out iris location,and then using multi-pass Gabor filters extract iris feature. Experiments show that the algorithm effectively overcome the Daugman algorithms Central Africa bright spot caused by scattering of artificial light effects,but also enhance the practicality and adaptability of iris recognition.
