An Adaptive Video Watermarking Based on Decomposing of Bit Planes
Zhigang Sun, Hua Jiang · 2009
Aiming at the conflict between robustness and invisibility of video watermarking system, a new adaptive video watermarking based on decomposing of bit plane was proposed in this paper. The bit planes of watermark were embedded in different quantity of intermediate and low frequency DCT coefficients because of the different weights in the process of watermark reconstruction. Meanwhile, the embedding strength was adaptively adjusted depending on luminance masking of HVS (Human Visual System). Watermark was adaptively embedded in video. Experimental results show that the presented video watermark scheme was robust and highly transparent.
