A Video Watermarking Algorithm Based on DTCWT Texture Analysis
Xianghong Tang · Journal of Hangzhou Dianzi University · 2008
In this paper,we propose a video watermarking algorithm based on texture object in MPEG-4 and the dual-tree complex wavelet transform(DTCWT).The watermark is embedded in the texture areas extracted by DTCWT,which is used to classify video texture.Simulation results show that the proposed algorithm realizes the watermark has the same properties of stochastic operational with video object,and is robust to the additive Gaussian noise,MPEG coding at high compression ratio,frame swap and frame drop.
