VIDEO CLASSIFIER CONSTRUCTION METHOD WITH CONSIDERATION OF CHARACTERISTIC RELIABILITY

摘要

The present invention provides a video classifier construction method with consideration of characteristic reliability, comprising: extracting video characteristics of each video sample in a video sample set to obtain a video characteristic set; granting a label to each video sample to indicate whether the video sample belongs to a first category or a second category; carrying out reliability evaluation on each video sample to obtain a reliability factor of each video sample; according to the video characteristic set, the label of each video sample and the reliability factor of each video sample, utilizing a weighted support vector machine algorithm to obtain a video classifier. The video classifier construction method is applicable to services of Internet harmful video filtration and video supervision so as to maintain the safety of content on the Internet.
