Content-based Video Retrieval by Dynamic Color and Motion Information

概要

論文の詳細を見る
This paper presents efficient and automatic color and motion feature extraction algorithm for content-based MPEG-1 video retrieval. Based on the proposed method, a video retrieval system is implemented. For color feature, the proposed algorithm considers dynamic color information in video data, and thereby can overcome the limits of the previous key-frame based method. For motion feature, we utilize the motion vector in MPEG-1 video with color information, and extract the color-motion feature. The proposed algorithm can solve the weakness of the previous location based motion feature method. Finally, the proposed method is evaluated within the implemented video retrieval system.
