Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0046] In order to solve the serious problem of difficult face recognition with masks, we designed a new module in the actual algorithm to reduce the interference of the background (including hair, masks, and areas other than the face) on the accuracy of the algorithm during face image preprocessing , let the algorithm pay attention to the feature extraction of the visible region of the face. Finally, the performance of the face recognition algorithm for mask occlusion is impr...

Abstract

The invention discloses a mask face recognition method and system based on background filtering, and the method comprises the steps of carrying out the preprocessing of a face image, and obtaining a face shielded image which comprises a mouth shielded image and an eye shielded image; based on the face image training and the data, training a first face recognition model used for recognizing that the face is not shielded, training a second face recognition model used for recognizing that the mouth is shielded, and training a third face recognition model used for recognizing that the eyes are shielded; performing facial feature vector fusion on the three types of face recognition models; and recognizing the human face by using the fused facial feature vector. According to the invention, interference of a background on algorithm precision is reduced during face image preprocessing, and the algorithm is enabled to pay attention to feature extraction of a face visible region; a plurality ofrecognition models are used for training and finally fusion is performed so that the recognition performance of the face recognition algorithm under the condition of face shielding can be enhanced.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a face recognition method and system for face masks based on background filtering. Background technique [0002] Since 2020, affected by the 2019 novel coronavirus, the whole country has entered a state of emergency epidemic prevention. In order to prevent the spread of pathogens, everyone is required to wear masks, wash hands frequently, and go out less. However, the resumption of work is also urgent. During the resumption of work, it is also necessary to closely observe people's physical conditions, find suspicious symptoms, and be able to be controlled in time. However, if this large-scale task is completely handled by relevant staff, it may fall into an embarrassing situation of insufficient staff. . [0003] Therefore, a standardized temperature measurement and supervision process is essential. It is indeed a good idea to use the non-contact reporting mec...
