Embodiment 1

[0029] figure 1 A schematic flow chart of a method for detecting violations of regulations provided by Embodiment 1 of the present invention is given. The method is suitable for detecting violations of live video streams. The method can be executed by a device for detecting violations of regulations, wherein the device It can be implemented by software and / or hardware, and generally can be integrated on a computer device.

[0030] It should be noted that the execution subject that executes the method provided in this embodiment can be used as a part of the live broadcast review system on the live broadcast platform to determine in real time whether the live video generated when the host interacts with the audience on the live broadcast platform contains illegal content.

[0031] like figure 1 As shown, a violation video detection method provided in Embodiment 1 of the present invention specifically includes the following operations:

[0032] S101. According to the target int...

Embodiment 2

[0066] image 3A schematic flow diagram of a method for detecting video violations provided by Embodiment 2 of the present invention is given. This embodiment is optimized on the basis of the above embodiments. In this embodiment, the method further obtains the currently intercepted video frame to be detected. Afterwards, the optimization also includes using the selected target similarity algorithm to determine the target similarity value between each valid video frame that has been intercepted in the video stream to be detected and the intercepted video frame.

[0067] At the same time, on the basis of the above-mentioned optimization in this embodiment, it may further include: if it is determined that the intercepted video frame does not meet the violation detection condition, then determine a target effective intercepted frame that matches the intercepted video frame, and effectively intercept the frame according to the target The violation detection result determines the d...

Embodiment 3

[0110] Figure 5 A structural block diagram of an illegal video detection device provided by Embodiment 3 of the present invention, the device is suitable for the case of illegal detection of live video streams, wherein the device can be implemented by software or hardware, and generally can be integrated in on the computer device. like Figure 5 As shown, the device includes: a video frame acquisition module 31 and an illegal content detection module 32 .

[0111] The video frame acquisition module 31 is used to obtain the current intercepted video frame to be detected according to the target interception interval time corresponding to the received video stream to be detected;

[0112] The illegal content detection module 32 is used to detect the illegal content of the intercepted video frame when it is determined that the intercepted video frame satisfies the violation detection condition, and record the intercepted video frame as a valid intercepted frame;

[0113] Where...

Abstract

The embodiment of the invention discloses a prohibited video detection method, a device, equipment and a storage medium. The prohibited video detection method comprises the steps of a current to-be-detected intercepted video frame is obtained according to target interception interval time corresponding to a received to-be-detected video stream; when it is determined that the intercepted video frame meets the violation detection condition, violation content detection is performed on the intercepted video frame, and the intercepted video frame is recorded as an effective intercepted frame; wherein the violation detection condition is that the target similarity values of all the intercepted effective intercepted frames and intercepted video frames in the to-be-detected video stream are smaller than a set similarity threshold value. Compared with the prior art, the method has the advantages that the video frames in the short-time-length video can be effectively intercepted by the selectedinterception interval time, so that the flash leakage amount of prohibited video frames is reduced; meanwhile, violation detection is carried out on the video frames meeting violation detection conditions, so that the detection cost is reduced, and missing detection of the violation video frames is better avoided on the premise that the detection cost is not greatly increased.

Description

technical field [0001] The embodiments of the present invention relate to the field of live broadcast technology, and in particular, to a method, device, device, and storage medium for illegal video detection. Background technique [0002] With the development of multimedia and mobile Internet technology, multimedia traffic has increased significantly in recent years, and new entertainment methods such as live broadcast and short video have attracted widespread attention and participation. At the same time, many videos mixed with illegal content (such as pornography, violence, etc.) are spread in the form of multimedia live broadcast, disrupting people's normal life, and at the same time having a negative impact on the live broadcast platform and platform users. [0003] For the detection of illegal content, the earliest method is to detect the video through manual review. However, due to the large amount of video resources in the live broadcast platform, relying solely on m...
