Abstract

The invention provides a method and device for evaluating the quality of an iris image, comprising: acquiring an iris image to be evaluated; calculating a pixel occlusion rate of the iris image according to the iris image; and evaluating the quality of the iris image according to the pixel occlusion rate. According to the above scheme, by calculating the pixel occlusion rate of the iris image, the quality evaluation of the iris image is carried out. Since the quality of the iris image is evaluated by using the pixel occlusion rate, the efficiency is high, and the iris image with unqualified quality can be quickly removed, so that The accuracy rate is improved by using qualified iris images for application.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for evaluating the quality of an iris image. Background technique [0002] With the rapid development of computer technology, the technology of using iris image for identification has been realized. Among them, iris recognition technology is a technology based on iris image for identity recognition, which can be applied to security equipment, such as access control, and places with high confidentiality requirements. [0003] At present, before the iris image is collected for application, the quality evaluation of the iris image is not carried out, resulting in a high error rate when the iris image with unqualified quality is used for application. Contents of the invention [0004] In view of this, the present invention provides a method and device for evaluating the quality of an iris image, so as to solve the problem of high error rate in the prior art w...
