matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如未修改，可提取隐藏信息。当有修改发生时，可以定位修改的位置，并在图上标出。标识面积占修改面积的75％，一般修改都能标出(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, if modified, can extract hidden information. When a modification occurs, you can modify the location of positioning and marked maps. Logo area accounted for 75 to amend the area generally can be identified modifications)

FSIM图像质量评价性能指标算法，衡量图像质量好坏程度(FSIM image quality uation performance index algorithm, to measure the degree of image quality )

在文档下打开一个位图文件，重新绘制，放大并使其二值化显示，()

说明：  都是各向异性扩散用于图像去噪的文章，中文文献，看起来比较方便(Are anisotropic diffusion for image denoising article, Chinese literature, it seems more convenient)

contourlet 区域统计法，进行图像融合(contourlet regional statistical method for image fusion)

8*8矩阵dct变换以及量化 反量化和反dct变换(8* 8 transform and quantization matrix dct quantization and anti-anti-dct transform)

说明：  SAD立体匹配程序，附带测试图像.立体匹配学习的好内容。(SAD stereo matching process, attached to the test image. Stereo Matching learn the content.)

outguess 隐写源码，用于对于图像上附加秘密信息 (outguess steganography source code for additional confidential information for the image)

对图像矩阵进行zigzag扫描,从而达到对图像纹理（灰度值）置乱的效果。( scanning of the image matrix by Zigzag，To achieve the scrambling effect of the image texture (gray value).)
