Problems solved by technology

However, if the traditional iris image feature extraction and comparison process is still used on mobile devices, many extracted features will be the high-frequency noise of the image instead of iris details, thus losing its high-complexity meaning

Abstract

The invention aims at providing a four-dimensional analysis-based biological feature recognition method and a four-dimensional analysis-based biological feature recognition system. The method is characterized by comprising the following steps of acquiring an image with biological features to serve as a target image; preprocessing the target image; performing image comparison on the preprocessed target image and a reference image preregistered so as to obtain an image energy residual value between the target image and the reference image, wherein the image comparison comprises comparison between a designated comparison area in the target image and a corresponding comparison area in the reference image; when the image energy residual value is less than or equal to a preset threshold value, determining that the target image and the reference image are matched, and otherwise, determining that target image and the reference image are unmatched.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a biometric feature recognition technology based on four-dimensional analysis. Background technique [0002] The application of biometric technology in the field of identification is expanding. Biometric identification technology uses the imaging of users' inherent biological characteristics such as fingerprints, irises, and veins as the basis for identity confirmation. Compared with traditional identification methods such as passwords or identity cards, biometric identification technology has many advantages such as individual uniqueness, no need for memory, difficult to be stolen, convenient operation, and high security level. Especially on mobile terminals such as smartphones, tablets, and laptops, biometric technology, as a safe and convenient means of identification, has a tendency to replace traditional means of identity verification. In the biometric identifica...
