摘要：Due to complex computation and poor real-time performance of the traditional iris recognition system,iris feature is extracted by using amplitude and phase information of the mean image blocks based on Gabor filtering on image,and the k-nearest neighbor algorithm is combined to complete iris recognition *** recognition reduces the recognition time and improves the recognition *** the same time,identification result is transmitted to the cloud server through ZigBee network to solve diffcult wiring *** experiment shows the system runs stably and has fast recognition *** has been applied to a security system.
