Abstract: The algorithm applied to video watermark based on the property of the video is rare recently . This article brings the video property and HVS into the video watermark，gives an new algorithm， improve the capability of the watermark.

Abstract: LS-SVM (Least Squares Support Vector Machine) is simple and has a good ability of non-linear regression. As inputs of LS-SVM, DC-Energy-Ratio and Deviation of image samples are extracted first. Output of LS-SVM is the current texture classification. The results show that LS-SVM classifies images accurately by training the proposed two features.
