Abstract :
A robust video object based watermarking scheme is proposed in this paper. The video object is firstly segmented from the video streams, and then the synchronization problem can be solved by video object normalization. The permuted logo watermark or Gaussian distributed watermark is embedded into the middle frequency bands of the DWT domain of the video object. Watermark detection can be scaled by the normalized correlation coefficient. The theoretical analysis and experimental results show good robustness of the proposed scheme against object manipulations and MPEG compression.
