Problems solved by technology

In these scenarios, although the accuracy of face recognition is very high, the user's degree of freedom is not high. Users can only use it to identify their own identity, and cannot choose other video streams or human objects to be detected.
For example, if a user wants to select a video clip containing a specified character from a work shot by himself, or a video clip containing a favorite actor from a film and television work, there is a lack of relevant application software.

Embodiment Construction

[0034] In order to facilitate the understanding and implementation of the present invention by those of ordinary skill in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0035] Please see figure 1 , The present invention provides a method for screening face recognition video clips based on key frame backtracking, including the following steps:

[0036] Step 1: Extract frame images of the video stream to be detected;

[0037] According to the start position StartFrame and the end position EndFrame, the to-be-detected video stream Video is converted into the original frame image SourceFrame frame by frame;

[0038] Step 2: Preprocess the frame image to obtain the processed frame image FaceNormal;

[0039] Please see figure...

Abstract

The invention discloses a face recognition video clip screening method and system based on key frame backtracking. The method mainly comprises the steps of automatically constructing a key frame backtracking face recognition method of a sample set according to a multi-pose face composite detection method, providing a method for selecting a specified character segment from a video according to a modular design principle, and constructing a set of video analysis, screening and segment selection system. According to the method and the system, a video clip containing a specified person can be accurately selected from a to-be-tested video stream, and the requirement of computer-aided manpower for video information screening in the background of the information explosion era is met.

Description

Technical field [0001] The invention belongs to the technical field of face recognition, and relates to a face recognition video segment screening method and system, in particular to a face recognition video segment screening method and system based on key frame backtracking. Background technique [0002] Face recognition refers to the computer technology that uses the analysis and comparison of the visual information of the face for identity authentication. Generally speaking, a face recognition system includes image acquisition, image processing, face detection, and face recognition. [0003] Face detection is an important part of the process of face recognition. The current face detection methods can be divided into knowledge-based methods, statistical model-based methods, and pattern matching-based methods. [0004] At present, the commonly used methods in face recognition include geometric feature method, subspace analysis method, statistical feature method and so on. Althoug...
