The domain block video watermarking scheme based on video sequences' characteristics and DCT

This paper proposes an improved discrete cosine transform (DCT) domain block video watermarking scheme which based on the video sequences' characteristics. The watermarking scheme fully considered the characteristic of human visual system and moving object detection technology, and chose the movement and complex field as embedding regions. In the watermarking embedding process, we used the sub-pixel blocks to reduce the block effects of pixel classification.
