Problems solved by technology

This recognition method is a static recognition method, which relies on the independent comparison results of each frame image, so when the quality of some frame images in the video is not high, the face detection result is inaccurate, or the angle of the face in it When there is no corresponding sample in the face database, it will affect the accuracy of recognition, resulting in low recognition accuracy

Abstract

The present invention provides a face identification method in a video and a face identification device in the video. The face identification method in the video comprises the steps of carrying out the feature extraction on the target faces in multiple frames of images of the video to generate a plurality of feature vectors corresponding to the target faces in the multiple frames of images respectively; carrying out the timing sequence feature extraction on the plurality of feature vectors to transform the plurality of feature vectors into a feature vector of a predetermined dimension; utilizing a classifier to judge the feature vector of the predetermined dimension to identify the target faces. The face identification method and device in the video adopts a dynamic identification mode, and the information of the frames of images are complemented by utilizing the feature that the frames of images in the video have relevance on a time dimension, thereby improving the face identification accuracy.

Description

technical field [0001] The present disclosure generally relates to image processing and pattern recognition, and specifically relates to a face recognition method and device in video. Background technique [0002] In recent years, face recognition in video has become a very active research direction in the field of face recognition. Face recognition technology in video has broad application prospects in many aspects such as security monitoring, intelligent identity authentication, and home entertainment. Generally speaking, face recognition in video refers to the feature extraction of the face area detected in each frame image in the video, and then compares the features extracted in each frame with the existing face database. Finally, the identity of the face is identified according to the comparison result. [0003] The existing video face recognition methods usually take out the images in the video frame by frame, and compare and recognize the faces in each frame of the...
