数字图像处理中的基本形态学处理，如腐蚀、膨胀、开操作、闭操作等实现的源代码。可以自定义结构元素的形状。(Digital image processing in the basic morphology processing, such as corrosion, swelling, open operation and close operation to achieve the source code. You can customize the shape of structural elements.)

SIFT，即尺度不变特征变换（Scale-invariant feature transform，SIFT），是用于图像处理领域的一种描述。这种描述具有尺度不变性，可在图像中检测出关键点，是一种局部特征描述子。 该方法于 1999 年由 David Lowe 首先发表于计算机视觉国际会议（International Conference on Computer Vision，ICCV），2004 年再次经 David Lowe 整理完善后发表于 International journal of computer vision（IJCV） 。截止 2014 年 8 月，该论文单篇被引次数达 25000 余次。(来自百度)(SIFT, namely Scale-invariant feature transform (SIFT), is a description used in the field of image processing. This description has scale invariance and can detect key points in images. It is a local feature descriptor. This method was first published by David Lowe at the International Conference on Computer Vision (ICCV) in 1999 and published in the International Journal of Computer Vision (IJCV) in 2004 after it was sorted out and perfected by David Lowe again. As of August 2014, more than 25,000 citations have been cited. (From Baidu))

上课时做的一个小程序，表达式计算程序，采用vc++，可能有点儿小瑕疵，但基本运行是没问题的(Class to do a small procedure, expression of the calculation procedure for the vc++, may be a bit small flaws, but the basic operation is no problem of)

说明：  可改变中心时移，相位，主频的雷克子波，自己在源程序上加减时间，改变主频，加减相位即可(ricker wavelet which time,phase and frequence can be changed )

matlab写的一个经典的用于计算光流的工具箱。(Matlab write a classic optical flow used in the calculation of the toolbox.)

Gabor滤波器的实现函数，与一般网上下载的不同，滤波效果更好，易于提取图像特征(Gabor filter implementation function, and general downloading different, better filtering, easy to extract image features)

说明：  本程序在EVC4.0+PPC SDK 2003下调试通过。用Independent JPEG Group发行的JpegLib进行Jpeg图像的读取与保存。(This procedure in EVC4.0+ PPC SDK 2003 adopted under the debugger. By Independent JPEG Group issued JpegLib to read Jpeg images and preservation.)
