有关于数字图像处理基础内容，图像锐化，图像平滑，图象旋转，dct变换，idct变换

matlab 高动态图像 读取的hdr格式的读取文件，经测试可以用(matlab read hdr high dynamic image to read the file format, the test can be used)

基于Gabor的特征提取,gabor滤波器的构造 包含中科院的虹膜库(base on gabor zhongkeyuandehongmoku)

设置位置断点跟踪程序，VC++精选编程源码，很好的参考资料。(Set breakpoint location tracking procedures, VC++ programming source code, a good reference.)

说明：  基于hessian矩阵的frangi血管增强算法(An algorithm of vascular enhancement based on Hessian matrix)

sift匹配算法 尺度不变变换 特征描述子 特征点匹配 (sift match)

基于边界约束和上下文正则化的图像快速去雾算法(Effi cient Image Dehazing with Boundary Constraint and Contextual)

数字水印技术的matlab实现，一个简单的水印算法，注意自己修改图片名(Digital watermark technology matlab to achieve a simple watermarking algorithm, pay attention to their own to modify the name of the picture)

显示BMP图片，并绘制直方图。程序无误，可运行。(Display BMP image, and draw the histogram. Program is correct, you can run.)

说明：  图像去雾可以还原图像的颜色和能见度，同时也能利用雾的浓度来估计物体的距离，这些在计算机视觉上都有重要应用(Image Fog can restore the color and visibility of the image, but also can use the concentration of the fog to estimate the distance of the object, which have important applications in computer vision)
