Abstract

The invention relates to an image processing method and device, electronic equipment and a storage medium. The method comprises the steps: obtaining an iris image group which comprises at least two iris images to be compared; detecting an iris position in the iris image and a segmentation result of an iris region in the iris image; performing multi-scale feature extraction and multi-scale featurefusion processing on an image region corresponding to the iris position to obtain an iris feature map corresponding to the iris image; and executing comparison processing by using the segmentation results and the iris feature maps corresponding to the at least two iris images, and determining whether the at least two iris images correspond to the same object based on a comparison result of the comparison processing. According to the embodiment of the invention, accurate comparison of iris images can be realized.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, and in particular to an image processing method and device, electronic equipment, and a storage medium. Background technique [0002] Iris recognition technology uses the lifelong stability and unique differences of the iris for identity authentication. The superiority of iris recognition makes it have great application prospects in various aspects such as finance, e-commerce, security, and entry-exit control. [0003] Current iris recognition algorithms generally use filters to extract iris features. However, this method cannot fully obtain the characteristics of the iris, resulting in unsatisfactory iris recognition accuracy. Contents of the invention [0004] The disclosure proposes an image processing technical solution. [0005] According to an aspect of the present disclosure, an image processing method is provided, which includes: acquiring an iris image group, the ir...
