According to the increasing popularity of video-sharing websites,
copyright infringed videos have become a critical issue. These videos are
not only original ones, but also copied ones. Under these circumstances, the importance of video detection technology has increased.
In our earlier studies, we had proposed the (single) direct-mapped cache
method based on the RGB color space feature to handle the processing of
a large amount of videos on the Internet. Although our method achieved
a high processing speed, the detection accuracy had room for improvement.
In this paper, we proposed a new method to improve the accuracy.
For this purpose, the combination of MPEG-7 video signature and the multiple direct-mapped cache method is used. The experimental results show that the average detection accuracy is 95\%, and the processing time is 0.2 seconds for each video. These results indicate a 29\% improvement in accuracy over the previous method. |
