An video watermarking algorithm based on wavelet domain

In this paper, an video watermarking algorithm that based on wavelet domain is proposed. In order to enhance the robustness of the watermark, we propose to classify the wavelet coefficients based on the motion of the objects and the texture complexity of the contents in the video sequence. According to the result of classification and the correlation of frames, the watermark is adjusted adaptively and inserted into the coefficients of the wavelet transform low-frequency subband. The experimental results show that the proposed watermarking algorithm has good robustness to video degradation and distortion.
