A rotation resistant digital watermarking for video

摘要

This paper presents a rotation resistant digital watermarking procedure for video. Our watermarking procedure is based on the 3D DCT transform and video scene segmentation. The video stream is parsing into video scenes. A block sequence is got From every scene. By direct spread spectrum technique, a sequence of watermarks is generated from a watermark image and is adaptively added into the 3D DCT coefficients of the block sequence, the experimental result demonstrates the robustness of our video watermarking procedure to several watermarking attacks especially rotation.
