Abstract

This application relates to the field of image processing, in particular to a method for generating facial expressions for face recognition. After facial recognition is used to identify facial feature points in pictures or photos, different expressions can be calculated according to the feature points. Generate pictures with different expressions, so that real face photos can be placed on the preset model face for real-life role-playing, and facial recognition can also be used to communicate with virtual images.

Description

technical field [0001] The present application relates to the field of image processing, and in particular to a method for generating facial expressions for facial recognition. Background technique [0002] Face recognition technology is based on human facial features, and judges whether there is a face in the input face image or video stream. If there is a face, it further gives the position, size and main facial organs of each face. location information. Based on this information, the identity features contained in each face are further extracted and compared with known faces to identify the identity of each face. [0003] Specifically, face recognition includes face image acquisition, face location, image preprocessing, identity confirmation, and identity search. For example: facial capture of digital cameras, security access control system, network application identity verification, facial expression recognition, etc. Among them, the face capture of the digital camera...
