- W2157879442 abstract "The applications of video on Internet or wireless networks become very popular nowadays. However, these digital contents can be easily modified and copied by end users. Hence copyright protection, copy protection and integrity verification have become important issues in recent years. This paper proposes a novel blind watermarking algorithm based on feature points detected in MPEG-2 video. In this algorithm, Corner is defined as feature point. The position of watermark embedded is decided by the corners which are found by using Harris Detectors. And then combined with MPEG-2, the watermark is embedded by adjusting the 8*8 block DCT's DC coefficient. The experimental results show that compared with the original video, the watermarked video sequence is changed slightly; the PSNR of watermarked frames loses a little. Especially the proposed algorithm has strong robustness towards frame deleting and MPEG-2 compressing." @default.
