Embodiment 1

[0052] figure 1 It is a flow chart of a video recognition method provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the video recognition method includes:

[0053] Step 1001: Segment the video according to the shot segmentation technology to obtain multiple shot segments.

[0054] Step 1002, perform face recognition on the shot clips to identify the shot clips where a specific person is located.

[0055] Step 1003, mark the shot segment where the specific character is located.

[0056] Generally speaking, television and movie videos are formed by shooting one shot, so these videos are usually composed of multiple shot clips, and the shot clips include multiple video frames. The picture images of the video frames in the same shot segment are consecutive, and there is a very obvious switch between the end frame of the previous shot segment and the start frame of the next shot segment. Therefore, the end frame of the previous shot segment and the s...

Embodiment 2

[0064] figure 2 It is a schematic structural diagram of a video recognition system provided by Embodiment 2 of the present invention. Such as figure 2 As shown, the video recognition system includes a first segmentation unit 101 , a first recognition unit 102 and a first labeling unit 103 . The first segmentation unit 101 segments the video according to the shot segmentation technology to obtain a plurality of shot clips, the first recognition unit 102 performs face recognition on the shot clips to identify the shot clips where a specific person is located, and the first labeling unit 103 Annotate the shot clip where the specific character is located.

[0065] Generally speaking, television and movie videos are formed by shooting one shot, so these videos are usually composed of multiple shot clips, and the shot clips include multiple video frames. The picture images of the video frames in the same shot segment are consecutive, and there is a very obvious switch between t...

Abstract

The invention discloses a video identification method and a video identification system. The video identification method comprises the following steps: segmenting a video according to a lens segmentation technology so as to obtain multiple lens fragments, and performing face identification on the lens fragments so as to identify lens fragments where a specific person is disposed. According to the technical scheme provided by the invention, through combination of a face identification technology and the lens segmentation technology, various limitations of a conventional mode of video identification only by use of the face identification technology can be overcome. According to the invention, it is the lens fragments rather than frames that are taken as identification objects. In a whole lens segment, the lens fragment where the specific person is disposed can be identified as long as an identifiable face appears once no matter whether the profile and the back side of the specific person can be identified. The lens fragment where the specific person is disposed can be marked and correlation data of the specific person can be counted according to the identified face, such that the identification precision of the specific person is improved and the marking precision and the statistical precision are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a video recognition method and a video recognition system. Background technique [0002] In the prior art, face recognition technology is usually used to identify the characters in the video. The specific recognition process is as follows: obtain the video frame, detect the face in the video frame to obtain the face image in each video frame and related information, positioning and aligning the face image, extracting features from the face image to obtain face features, and matching the extracted face features with preset face features to identify a specific person. [0003] However, the existing face recognition technology requires the face of a specific person to appear in the video screen in a frontal form. Accurate or even unrecognizable. Contents of the invention [0004] In order to solve the above problems, the present invention provides a video recognition method and...
