ICIP 2003, IEEE International conference on image processing, September 14-17, 2003, Barcelona, Spain
This paper proposes a new video watermarking scheme based on a hierarchical motion analysis, that is robust against classical video processing (filtering, lossy compression...). This model works in the uncompressed domain and disturbs the motion vectors computed by an exhaustive BMA on blocks of size n*n in order to insert an invisible watermark enabling a protection against most attacks. Finally, to increase the robustness, our system inserts the mark by generating a hierarchy of motion vectors of size N*N with N=k*n to spread the mark on the lower level associated to block n*n.
