Abstract
To coding watermarking solve based robustness insufficiency of video watermarking based on H264/AVC caused by only embedding 1 bit watermark in one coefficient of macro block,this paper put forward a new energy- differential video coding watermarking algorithm based on textural features by considering the properties of H.264 compression standard. The proposed algorithm firstly performs the 4×4 integer DCT on the current frame aming at identifying whether it is the texture block or not. Then the watermarking is embedded by adopting the way of differential energy for selecting the appropriate coefficients adaptively. The experimental result shows that the proposed algorithm has little impact on the video quality and bit-rate, moreover, its robustness can effectively resist the common attacks such as the gauss noise, low pass filter and re-coded performed on the video watermarking.
