Embodiment 1

[0061] An embodiment of the present invention provides a video review method. Such as figure 1 Shown is a flow chart of the video review method of the present invention. Video examination method of the present invention comprises the steps:

[0062] S101. Intercept a multimedia segment of the video to be reviewed according to a scene in the video to be reviewed.

[0063]The embodiment of the present invention adopts the scene detection technology. First, the video to be reviewed is divided according to the scene. According to the duration of the scene, when intercepting the multimedia segment, different interceptions are made according to the type of the multimedia segment. For example, when the image frame is intercepted, it can be randomly selected. Several image frames, when intercepting audio clips, can intercept a piece of audio in a scene, and can also intercept all audio in a scene. Among them, a scene can be regarded as a series of continuous image frames, and the d...

Embodiment 2

[0073] On the basis of Embodiment 1, this embodiment of the present invention provides a video review method. Such as figure 2 Shown is a flow chart of the video review method of the present invention. Video examination method of the present invention comprises the steps:

[0074] S201. Intercepting image frames of the video to be reviewed.

[0075] S202. If the image frame may belong to a forbidden category, judge whether the image frame belongs to the forbidden category according to a preset forbidden category classification table.

[0076] In the embodiment of the present invention, in order to determine whether the image frame has the possibility of belonging to the prohibited category, the image frame is classified in detail, and the prohibited category classification table is shown in Table 1:

[0077] Table 1:

[0078]

[0079]

[0080] Obviously, the special category and cartoon normal in Table 1 do not belong to the prohibited category, the pornographic deg...

Embodiment 3

[0085] On the basis of Embodiment 1, this embodiment of the present invention provides a video review method. Such as image 3 Shown is a flow chart of the video review method of the present invention. Video examination method of the present invention comprises the steps:

[0086] S301. Extract an audio segment of the video to be reviewed.

[0087] S302. Extract the frequency spectrum of the audio segment of the video to be reviewed.

[0088] For example, in the embodiment of the present invention, 20,000 audio clips are collected and marked, and then artificial intelligence algorithms such as RNN and CNN are used for training to obtain an audio recognition machine model. The audio spectrum is analyzed by an audio recognition machine model.

[0089] S303. Determine whether the audio clip belongs to the forbidden category according to the frequency spectrum of the audio clip.

[0090] In the embodiment of the present invention, after extracting the voice segment of the vid...

Abstract

The invention provides a video review method and device and a server. The method comprises the following steps of intercepting a multimedia fragment of a to-be-reviewed video according to a scene in the to-be-reviewed video; detecting whether a content of the multimedia fragment belongs to a prohibited category or not; and if yes, sending prompt information of the to-be-reviewed video to the prohibited category, wherein the multimedia fragment comprises an image frame, an audio fragment, a speech fragment and/or a text fragment. The method can be realized by intercepting the multimedia fragment of the to-be-reviewed video according to the scene in the to-be-reviewed video and detecting whether the content of the multimedia fragment belongs to the prohibited category or not, wherein the multimedia fragment comprises the image frame, the audio fragment, the speech fragment and a character fragment, the to-be-reviewed video is cut into the multimedia fragment according to the scene, and when one fragment has relatively strong characteristic performance, the to-be-reviewed video can be determined to belong to the prohibited category, and the technical scheme can greatly improve the review efficiency under a condition that the video is longer.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a video review method, device and server. Background technique [0002] With the prosperity and development of Internet technology, there are more and more video resources on the Internet. A lot of videos are mixed, especially some of the videos uploaded by users themselves. For example, some video clips contain pornography, serious violence, etc., or some videos involve copyright issues. In order to be able to filter bad videos, it is necessary to review the content of the video. [0003] In the traditional technology, the broadcasting and television industry mainly adopts the method of video review: using the broadcast control system to conduct multiple rounds of manual review of the video. Specifically, a closed or semi-closed centralized office space is provided for manual reviewers, and each reviewer is equipped with a workstation and video playback equipment, wh...
