Embodiment 1

[0066] see figure 1 , figure 1 It is a schematic flow chart of the detection method of bad content in the video disclosed by the embodiment of the present invention; figure 1 As shown, a method for detecting objectionable content in a video may include:

[0067] 101. Acquire a video file to be detected.

[0068] It can be understood that the video content of the video file to be detected consists of audio and video images. In some embodiments, the video file to be detected may be a video file that the user is about to play, and content detection is performed on it before playing, which specifically includes: receiving a playback instruction input by the user for the video file to be detected, and based on the playback instruction , calling the video detection interface to enable the device for detecting objectionable content in the video, and performing the step of acquiring the video file to be detected, wherein the video detection interface is implicitly associated with t...

Embodiment 2

[0093] see figure 2 , figure 2 It is another schematic flowchart of the method for detecting objectionable content in a video disclosed in the embodiment of the present invention; figure 2 As shown, a method for detecting objectionable content in a video may include:

[0094] 201. Acquire a video file to be detected.

[0095] Reference may be made to the detailed description in step 101, and details are not repeated here.

[0096] 202. Perform video and audio separation on the video file to be detected to obtain audio information and image information.

[0097] As an optional implementation manner, after obtaining the video file to be detected in step 201, and performing video and audio separation on the video file to be detected in step 202, before obtaining audio information and image information, the embodiment of the present invention also includes:

[0098] Obtain the file name of the video file to be detected;

[0099] Compare the file name with the list of sensi...

Embodiment 3

[0142] see image 3 , image 3 It is a schematic structural diagram of a device for detecting objectionable content in a video disclosed in an embodiment of the present invention; image 3 As shown, a detection device for bad content in a video may include:

[0143] An acquisition unit 310, configured to acquire a video file to be detected;

[0144] The separation unit 320 is used to separate the video and audio from the video file to be detected to obtain audio information and image information;

[0145] a text conversion unit 330, configured to convert audio information into first text content, and convert image information into second text content;

[0146] Merging and deduplication unit 340, configured to merge and deduplicate the first text content and the second text content to obtain the target text content;

[0147] A search unit 350, configured to compare the target text content with the list of sensitive words, find out the sensitive words in the target text conten...

Abstract

The embodiment of the invention relates to the technical field of video processing, and discloses a bad content detection method and device in a video. The method comprises the following steps: acquiring a to-be-detected video file; performing video-audio separation on the to-be-detected video file to acquire audio information and image information; converting the audio information into the first text content and converting the image information into the second text content; performing combination and duplicate removing processing on the first text content and the second text content to acquire target text content; comparing the target text content with a sensitive vocabulary list to find out sensitive vocabularies in the target text content and acquire the total number of the sensitive vocabularies; acquiring a bad content proportional value of the to-be-detected video file according to the total number of the sensitive vocabularies and the total number of the target text content; and processing the to-be-detected video file according to the bad content proportional value. Through the implementation on of the detection method disclosed by the embodiment of the invention, a recognition accurate rate of the bad content in the video is improved, and an error judgment rate of the bad video is lowered.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a method and device for detecting bad content in a video. Background technique [0002] Online video has penetrated into people's daily life and has become a means for people to obtain knowledge and entertainment. The content of online video covers a wide range, and the video content varies from good to bad, often mixed with bad content such as violence, reactionary or fraudulent information. With the dissemination of videos including inappropriate content, it will disturb the social order, destroy the social atmosphere, and cause a great negative impact on the healthy growth of people, especially young people. Therefore often need to check the content of network video, to filter out the network video of bad content. However, the amount of video information is usually relatively large, and the existing filtering methods cannot quickly screen out bad videos, which may e...
