Problems solved by technology

In image coding, the linear fusion between the grayscale image and the RGB channel image of the color image will lose part of the information of the original face image, so the description of the face image information is not accurate enough, resulting in the inaccuracy of the final face recognition , affecting the accuracy of face recognition

Abstract

Provided are a human face recognition method and human face recognition system. The method comprises the steps of acquiring original color images to be recognized, extracting channel color images, of preset channel types, of the original color images to be recognized, extracting corresponding image characteristics of all the channel color images respectively, carrying out dimension reduction processing on the image characteristics of all the channel color images to obtain image characteristics after the dimension reduction, carrying out cosine distance calculation on the characteristics, after the dimension reduction, of all the channel color images, and obtaining the final similarities of the original images through SVM fusion. According to the scheme, the human face information can be described from different angles, the accuracy of the description of the human face image information is improved, and application can be carried out in various human face verification and recognition occasions conveniently.

Description

technical field [0001] The invention relates to the field of face recognition, in particular to a face recognition method and a face recognition system. Background technique [0002] The application of human-computer interaction technology is becoming more and more extensive. In the field of human-computer interaction, face recognition technology is of great significance. As one of the main research methods in the field of pattern recognition and machine learning, a large number of face recognition algorithms have been proposed. In traditional face recognition applications, due to the influence of acquisition equipment and external light interference, the collected face images are usually represented as grayscale images or infrared images. Therefore, face recognition algorithms are usually aimed at single-channel grayscale images. Degree image is performed. In image coding, the linear fusion between the grayscale image and the RGB channel image of the color image will lose...
