Abstract

The embodiment of the present invention discloses a face recognition method under complex lighting scenes, relates to the technical field of image processing, and can improve the lighting robustness of complex lighting face recognition. The invention includes: loading the first to Nth illumination invariant algorithms, and extracting the first to Nth illumination invariants corresponding to the original image through the loaded illumination invariant algorithms. Among them, N is an integer greater than or equal to 2; linear discriminant analysis is performed on the extracted illumination invariants to obtain the algebraic features corresponding to each illumination invariant algorithm. Based on the obtained algebraic features, the combined algebraic features of the original image are obtained through a feature-level fusion algorithm. Classification is performed on the obtained algebraic features and the combined algebraic features by a classifier group to obtain a final recognition result of the original image. The present invention is applicable to face recognition under complex lighting scenes.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a face recognition method under complex lighting scenes. Background technique [0002] Face recognition under complex lighting scenes has always been a problem that requires continuous research and optimization in the industry. Image processing-based and machine learning-based recognition schemes are currently two commonly used methods to improve the robustness of face recognition in complex lighting. way. [0003] Due to the limitation of hardware computing efficiency (such as the performance limitation of the CPU and image processor on the mobile terminal), it is necessary to use as few samples as possible as the training set. Currently commonly used algorithms include MSR (Multi-Scale Retinex, multi-scale retinal model), GF (Gradientfaces, gradient face) and INPS (IlluminationNormalization By a Series of Processing, illumination normalization processing chain algorit...
