Embodiment Construction

[0011] Face recognition is currently a research hotspot in computer vision and machine learning, and has broad application prospects. How to obtain effective face feature expression and design a powerful classifier has become the key to research, but the uncontrollable factors in the actual environment increase the difficulty of acquisition. With the introduction and development of compressed sensing theory, the research on face recognition method based on sparse coding model has aroused extensive attention and great interest of researchers. First of all, a face recognition method based on Sparse Representation Based Classification (SRC) is proposed, which shows better performance in robust face recognition, and is good for face recognition with brightness changes, noise and occlusion. Has good effect. The basic idea is that if the training samples with known category attributes but belonging to different categories are vectorized in the airspace or its feature domain to form...

Abstract

The invention relates to a method for comparing the similarity of human faces. By extracting the feature points of the face image, dividing the feature blocks, including the feature points in the feature blocks, and extracting the feature blocks hierarchically, the feature points therein are For further extraction, calculate the proportion of similar blocks and matching feature points at the same time, so as to compare the similarity in two face images. This method has a large degree of practicability, and the comparison of the features of the face image is more detailed, and the comparison and calculation process is also more strict.

Description
