Description: The Discrete Wavelet Transform (DWT) is used in a variety of signal processing
applications, such as video compression , Internet communications compression
, object recognition , and numerical analysis. It can e_ciently represent
some signals, especially ones that have localized changes.

Description: In this paper, we propose a new method that use
side view video pre-processing with DWT-SVD based water-marking scheme. This processing switch the video references
of the frames with dimensions equivalent of the number of
frames like width and the same height than the original video.
The DWT-SVD watermarking is applied in.

Description: 该算法利用随机置乱的方法将水印信息进行置乱，对选定的视频帧先进行DWT变换，然后对得到的逼近子图进行DCT变换，最终将置乱后的水印信息嵌入到直流分量-The algorithm uses the method of random scrambling the watermark information is scrambling to be first selected video frames DWT transform, and then the resulting approximation diagram DCT, eventually scrambled watermark is embedded into the DC component
