As videos such as bloody, violent and pornographic could not be updated frequently, a new objectionable videos detection method based on the combination of machine detection and manual intervention was proposed. First, objectionable video was labeled by manual method. Then the normalized energy curve was calculated through the multiple color space and the video character database was set up. ... [Show full abstract] Finally, the system can automatical detect the objectionable videos by querying the video character database. Experiments show the method can accurately and quickly realize the detection and early warning of the objectionable videos.
