Embodiment Construction

[0048]Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0049] Such as figure 1 Shown, in one embodiment, a kind of video review method based on multi-level multi-model, comprises:

[0050] S11. Input the video picture obtained after processing the video stream into the first-level review model to obtain a first violation score.

[0051] In the embodiment of the present invention, the video picture obtained after processing the video stream is input to the first-level review model, and before the first violation score is obtained, the video stream needs to be segmented according to a preset s...

Abstract

The invention provides a video auditing method and device based on multiple levels and multiple models, a computer readable storage medium and computer equipment, and the method comprises the steps: inputting a video picture obtained after a video stream is processed into a first-level auditing model, and obtaining a first violation score; inputting the video picture of which the first violation score is greater than a first preset threshold into a second-level auditing model to obtain a second violation score; processing the second violation score according to a preset machine learning algorithm to obtain a final violation score of the video stream, and outputting an unqualified auditing result of the video stream when judging that the final violation score is higher than a second presetthreshold. According to the invention, a multi-level and multi-model structure and an xgboost fitting score mode are adopted, so the redundant overhead is reduced while multiple models are used, and the online video auditing efficiency is improved efficiently.

Description

technical field [0001] The present invention relates to the field of computers, in particular, the present invention relates to a multi-level and multi-model-based video review method, medium and computer equipment. Background technique [0002] Video review refers to screening and filtering some illegal videos. For example, some videos involving violence, terrorism and pornography are illegal videos. At present, the solution to the problem of low-quality video review is usually: process each frame of video data, input the image data of each frame and the corresponding label (violation or non-violation) of the frame to the deep neural network, and use the deep neural network to fit the violations respectively. Features of video data and normal video data. After getting the fitted model, you can input a video to the model, and the output is the violation probability of the video. [0003] However, there are at least the following defects in the existing technical solutions:...
