Abstract

The invention relates to the technical field of machine vision, and specifically discloses a face recognition method based on a central point tracking model, and the method comprises the steps: obtaining a plurality of frames of target images; performing face tracking on the target images of the front and back frames, and determining a corresponding tracking sequence ID; performing face alignmenton the face image of the tracking sequence ID, and extracting corresponding face features; after one tracking sequence ID is finished, constructing a pre-processing face ID sequence; performing quality evaluation on the face images in the pre-processed face ID sequence, and selecting face features in the first Num face images with the best quality as a cleaned face ID sequence feature group; and denoising face features in the face ID sequence feature group, and determining a final face recognition result through reordering of the face features. According to the method, the influence of factorssuch as illumination, pedestrian flow shielding and face angles on the face recognition effect in a dynamic video environment can be reduced, and the face recognition precision is improved.

Description

technical field [0001] The invention relates to the technical field of machine vision, and more specifically, to a face recognition method based on a central point tracking model. Background technique [0002] With the popularization of video surveillance systems and the rapid development of computer vision technology, video-based dynamic face recognition technology has made great progress, and has gradually realized industrialization in the fields of intelligent transportation, smart city, information security and security. [0003] The application scenario of the dynamic face recognition method is mostly video to static image recognition. The video to static image recognition often uses frame-by-frame face images as input, and compares them with the static image face database, according to cosine distance, Euclidean Fuse distance or majority vote to fuse the results of all frames for recognition or verification. On the one hand, this frame-by-frame comparison method consu...
