Abstract

The invention discloses a face recognition method and system with invariant and robust face attributes, comprising the following steps: S1, extracting face features; S2, estimating face attributes; S3, constructing and selecting a face attribute sub-dictionary; S4 , attribute unchanged face feature extraction; S5, face classification and recognition; the face depth feature extraction module in the system is connected with the face attribute recognition module and the face attribute dictionary construction module respectively, and the face attribute recognition module is connected with the face attribute successively The sub-dictionary selection module, the face attribute invariant feature extraction module, the face classification recognition module, and the face attribute sub-dictionary selection module are connected with the face attribute sub-dictionary selection module through the attribute over-complete dictionary. The invention can solve the face recognition under complex environments such as simultaneous changes in illumination, posture, expression, occlusion, and resolution of the face and their combined changes, and keeps the attributes of the face unchanged, with high robustness.

Description

technical field [0001] The invention relates to the field of image processing and pattern recognition, in particular to a face recognition method and system with invariant face attributes and robustness. Background technique [0002] After more than half a century of development, face recognition technology has made substantial progress and has reached the application level in a controlled environment. However, in practical applications, especially in extremely complex environments, it is found that it is still not perfect, and it is easily disturbed by comprehensive factors such as face lighting, posture, expression, occlusion, age and plastic surgery. For example, during the prevention and control of the new coronavirus epidemic, in order to adopt intelligent prevention and control measures, face detection and face recognition technology can be used to eliminate interference during remote body temperature screening, so that the system can only detect the forehead part of t...
