Abstract :
In this paper, a fast and robust video copy detection scheme is proposed, which is suitable for the DCT-coded video sequences. To address the efficiency and effectiveness issue, we extract the video signature directly from the compressed domain. The video sequence clusters are constructed with a fixed length. Each cluster consists of several fictional key-frames. For each key-frame, some low-middle frequency full DCT coefficients are obtained directly from block DCT coefficients, and their ordinal measure is computed and acts as video signature. A rotation compensational strategy is further employed to resist the rotation attacks. The experimental results show that the proposed scheme can be resilient to various types of video transformations, including scaling, rotation, speed change, text insertion, and subsequence insertion/deletion etc.. The most important thing is that the proposed approach not only handles geometric distortion perfectly, but also reduces the computation costs substantially.
