说明：  这个水印一般般利用DWT变换和DCT变换嵌入水印，加上了Arnold变换使图片水印的抗MP3压缩攻击有所提高。(The watermark in general as the use of DWT transform and DCT transform embedded watermark, coupled with the Arnold transform to image watermarking against MP3 compression attacks increased.)

This is a tutorial to help you get started in Matlab. To find more details see the very helpful book Mastering MATLAB 6 by Duane Hanselman and Bruce Littlefield. Examples of Matlab code in this pamphlet are in typewriter font like this. As you read through the sections below type and execute in Matlab all of the examples, either at the  command line prompt or in a test program you make called test.m. Longer sections of code are flagged with the characters begin and end. All of the Matlab code between these two

可以读取yuv文件，输入文件夹名字、图像尺寸、帧数等，为处理yuv文件的前提(Input: filename- YUV sequence file dims- dimensions of the frame [width height] numfrm- number of frames to read startfrm- [optional, default = 0] specifies from which frame to start reading with the convention that the first frame of the sequence is 0- numbered)
