AI Technical Summary
In existing technologies, when it comes to verifying the image to be verified, it is difficult to perform identity verification efficiently, especially when verifying fingerprints, palm prints, irises, finger veins, and palm veins. The verification efficiency is low, mainly because the calculation of the grayscale histogram similarity between the image to be verified and the template image is time-consuming.
By obtaining the directional grayscale values of the image to be verified and the template image, grayscale histograms of the directional images to be verified and the template images are generated using multiple preset filter groups, and their similarity values are calculated to determine the authentication result.
By reducing the number of bins in the grayscale histogram, the efficiency of identity verification is improved, the computation time is reduced, and the verification speed is increased.
