Problems solved by technology

However, with the maturity of face-changing technology, and the fact that only a part of the face is changed in some videos, the existing technology can no longer meet the current recognition needs of face-changing, and the recognition rate is low, and the face-changing cannot be accurately determined. The specific position of the face

Abstract

The invention discloses a face change recognition method, device and equipment and a medium. The method comprises the steps of collecting to-be-recognized face information of a first key frame in a first standard code stream file, wherein the first standard code stream file carries preset video information, and original face information corresponding to all the key frames in the first standard code stream file is recorded in the preset video information; extracting first original face information corresponding to the first key frame from the preset video information; and identifying whether the first standard code stream file is subjected to face change processing or not according to the overlap ratio between the to-be-identified face information and the first original face information. According to the technical scheme provided by the invention, the face changing processing is recognized according to the coincidence degree between the face information, and the recognition efficiency and the recognition precision of face changing recognition can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of face recognition, and in particular, to a method, device, device and medium for face-changing recognition. Background technique [0002] With the development of face recognition technology, many video face-changing technologies have gradually appeared. This technology can modify the face image in the video. Once it is used improperly, the data will be maliciously modified, which will violate the law and cause serious social damage. influences. [0003] In the prior art, the face-changing recognition is usually carried out by collecting the "anti-physiological" features of the face, for example, judging whether the face has been changed by judging whether the proportion of the head of the person in the image conforms to the normal proportion. However, with the maturity of face-changing technology, and the fact that only a part of the face is changed in some videos, the existing techn...
