Title: Method for iris liveness detection and related product
Inventor: ZHOU YIBAO
IPC: G06V10/143
Filed: 2018-06-11
Abstract: Provided are a method for iris liveness detection and a related product. The method comprises: acquiring an iris image (101); dividing the iris image into K regional images, K being an integer greater than 1 (102); using P iris liveness detection algorithms to perform liveness detection on the K regional images so as to obtain K detection results, P being an integer greater than 1 and not greater than K (103); and determining, according to the K detection results, whether the iris image is an image of a live iris (104). In the invention, an iris image is divided into multiple regions. An iris liveness detection algorithm is selected for each of the regions and used to perform liveness detection on the region so as to obtain multiple detection results. Whether the iris image is an image of a live iris is determined according to the detection results, thereby reducing a false detection rate associated with use of a single iris liveness detection algorithm, and increasing accuracy of iris liveness detection.
