In the macroblock coding mode selection process, to improve the judging speed of intra macroblock refresh, the codec usually uses the previous frame temporal information and low-level SVC layer image information to prejudge to reduce the range of candidate macroblock coding modes. As the compressed bitstreams are particular sensitive to error, in order to enhance the error resilience of compressed...
There are various traditional video watermarking schemes robust to geometrical transformations. Most of them use synchronizing techniques or invariant transforms to resist geometric distortions. However, these algorithms are time-consuming or not resilient to mixed geometrical distortions. In this paper, we propose a video watermarking method that is robust to compound geometrical attacks and has...
