Problems solved by technology

Judging whether a video image frame is a sensitive image mainly depends on the skin color information in the image, and skin color detection often lacks robustness when the image background is complex or the image quality is poor, resulting in a high false detection rate

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0026] The execution environment of the present invention is composed of the following four module groups: 1. Sensitive sound model building module, the function of this module is to learn sensitive sound samples to obtain model parameter data. 2. Audio and video separation module, the function of this module is to separate the audio data and video data in the film. 3. Feature extraction module, the function of this module is to extract the features of audio and video respectively. 4. Classification and fusion module. The function of this module is to classify audio and video features, and fuse the classification results to make comprehensive decisions on the sensitivity of the film. Overall frame of the pr...

Abstract

The invention relates to a method for detecting sensitive videos on the basis of an audio and video fusing strategy, which comprises the steps: building a mixed Gauss model of sensitive sound, separating audio data, adding a window, extracting characteristics, positioning a sensitive sound fragment, outputting the sensitive degree of the sensitive sound fragment, detecting a sensitive fragment video image frame, carrying out an audio and video fusing decision on the basis of Bayes, and the like. The method is combined with information of two modes of audio and video to filter the sensitive videos, the uncertainty which may appear due to adopting a single mode is greatly lowered, and the recognition efficiency is prominently improved. The method can be used to detect whether video streams on internet and audio-visual products contain sensitive contents or not and also can be used to monitor network video chat rooms, and eroticism performances can be obstructed once being discovered.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a sensitive film detection method. Background technique [0002] In recent years, with the rapid development of computers, especially Internet technology, the content and dissemination methods of sensitive information (mainly including pornographic novels, images and videos) have also undergone significant changes. People can now easily browse a large number of of such content. The widespread dissemination and easy acquisition of sensitive information has caused great harm to the majority of minors, and it is easy to affect the physical and mental health of young people and induce juvenile delinquency. Compared with sensitive text and image content, sensitive video is more harmful because its scenes are more realistic and the sensory stimulation brought by multimedia is stronger. How to make full use of the multi-modal information in the multimedia sensitive film ...
