Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] The present invention performs sensitive identification by acquiring single frame information of video and motion information between frames. Single frame information provides image features, and motion information provides motion features. The degree of skin exposure is obtained by color segmentation of the image through the skin color manifold classifier based on variational mixed Gaussian. Obtain the optical flow direction histogram through continuous image sequences to find out the motion characteristics of moving objects in the video. Make a comprehensive evaluation of the sensitivity of the entire video on the basis of image features and motion features.

[0025] Optical flow histogram to find motion features:

[0026] The generation of optical flow mainly comes from the relative motion between the camera and the environmental ob...

Abstract

A method form identifying sensitive video based on light stream direction histogram and skin color stream deformation score includes downloading original video and decompressing video, calculating motion character of each frame, calculating said histogram and classifying said histogram by histogram sorter, calculating image character and dividing skin color by sorter for judging whether skin colorratio is over threshold or not and judging that this frame is sensitive image if motion character and image character are both sensitive.

Description

technical field [0001] The invention relates to a method for monitoring network sensitive information, in particular to a method for video filtering. Background technique [0002] Mankind has entered the 21st century, which is a globally networked society. The penetration of the Internet into the global economy and social life has far exceeded people's expectations in terms of depth and influence. In the history of mankind, there has never been any technology and its application that has developed so fast as the Internet and has had such a great impact on people's work, life, consumption and communication methods. Moreover, with the advent of a highly informationized network society, people There will also be earth-shaking changes in terms of production and lifestyle, concepts and awareness. [0003] It seems that people are not fully prepared for the new environment created and provided by the Internet. Therefore, many people are more or less panicked about the series of ...
