Quick face recognition method and device

Abstract

The invention provides a quick face recognition method, apparatus and device, and a readable storage medium. The method comprises the steps of preprocessing and binarizing a to-be-recognized face image to obtain a binary image; performing right lower vertex detection on the binary image to obtain a right lower vertex set; synthesizing a synthesized face area corresponding to each right lower vertex according to a preset value, calculating to obtain an evaluation array according to face area extraction features, calculating a normal form evaluation value of each right lower vertex by adopting aface evaluation normal form, and selecting the right lower vertex with the maximum normal form evaluation value as an actual right lower vertex; and generating a target face area according to the actual lower right vertex and the face width and height, and intercepting a corresponding image from the to-be-recognized face image according to the target face area to perform face recognition. According to the invention, the human face is positioned by combining the right lower vertex detection and the human face evaluation normal form, the search range is reduced, and the influence of various interferences is reduced, so that the human face area can be quickly and accurately positioned for human face recognition.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a fast face recognition method, device, equipment and a readable storage medium. Background technique [0002] Face recognition is a technology for identity recognition based on human facial feature information. By extracting face features and comparing them with the existing feature information in the database, the comparison results are obtained, and then the identity is identified. At present, the accuracy of face recognition needs to be improved due to changes in the age of personnel and changes in makeup and posture. [0003] Invention Patent Application No. 201810919221.7 "A Face Recognition Method and Face Recognition System" involves a face recognition method and a face recognition system. When a person is detected within the recognition distance, the face picture is obtained and the face is extracted. Features, compare the extracted face features with m...

Problems solved by technology

[0004] However, this invention does not consider the interference from the uneven lighting of the face and the random and changeable background environment where the face is located, and it is often unable to recognize the face quickly and stably.
