Error detection in a compressed video using fragile watermarking
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 1 - Trang 129-132 vol.1
Tóm tắt
This paper proposes an error detection technique using fragile watermarking. The fragile watermark is embedded in the least significant bits of the selected transform coefficients decided to balance between deterioration of PSNR value and error detection efficiency. The proposed method is usable without additional bits in the video bitstream and can be implemented very efficiently. This method will be useful in an error prone environment like a wireless channel.
