Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0022] figure 1 The flowchart of the method for video detection based on semantic analysis provided by this application, including:

[0023] Obtain the video data stream, calculate the eigenvalue of the histogram of each frame in the gradient direction, and when the difference between the eigenvalues ​​between the frames is greater than the preset threshold, it is determined that an image appears between the frames Jumping, and inserting a label between the frame and the frame, the label is used to mark the point where the image jumps;

[0024] According to the label, extract the frame image at the moment after the label, input it into the seman...

Abstract

The invention provides a video detection method and system based on semantic analysis, and the method comprises the steps: obtaining an image jump point through calculating a feature value of a histogram of each frame in a gradient direction, carrying out the labeling through a label, inputting a frame image at a moment after the label into a semantic analysis model and a graphic analysis model in parallel, and judging whether the frame image is compliant or not. According to the method and the device, the non-compliant video images can be quickly identified and effectively processed.

Description

technical field [0001] The present application relates to the field of network multimedia, in particular to a method and system for video detection based on semantic analysis. Background technique [0002] With the rapid development of the Internet, a large number of video programs have appeared, enriching people's spare time life. But it also brings problems. Violence and other non-compliant content may appear in the video, which becomes a hidden danger that endangers society. In the face of non-compliant videos, due to the very fast transmission speed of the network, it is necessary to be able to quickly identify and effectively deal with them. At the same time, most of the existing technologies are text and image recognition methods, and lack of video recognition methods. [0003] Therefore, there is an urgent need for a method and system for video detection based on semantic analysis. Contents of the invention [0004] The purpose of the present invention is to prov...
