Abstract

The present invention provides a low-resolution face super-resolution and recognition method based on facial prior knowledge, including S1: building a data set; S2: performing face super-resolution to obtain a mapping matrix; S3: constructing Feature extractor, respectively map and to the public space; S4: obtain the corresponding mapping matrix; S5: obtain the prior knowledge of the image, and obtain multiple super-resolution results; S6: respectively map and to the public space, and Assign its category to; S7: finally generate the result of face super-resolution and recognition. Through the technical solution of the present invention, the content of the present invention mainly includes two parts, one is to train the face pair data set composed of low resolution and high resolution; Space to train a nonlinear transformer with the goal of improving the accuracy of low-quality face image recognition.

Description

technical field [0001] The present invention relates to the technical field of pattern recognition, in particular to a low-resolution human face super-resolution and recognition method based on facial prior knowledge. Background technique [0002] At present, face recognition technology has been relatively mature and its application research is very extensive, and it has spread to all aspects of modern social life. However, many face recognition systems work on the premise that the face object belongs to a high-quality image. Therefore, when the face in the real world is a low-resolution image due to various reasons, such as monitoring equipment, distance, etc., the system often exhibits poor performance and is not even recognized. Face super-resolution technology can enhance the resolution of low-resolution face images to generate corresponding high-resolution face images. Therefore, realizing the connection of face super-resolution and face recognition tasks can directly...
