An implementation of Lucas-Kanade optical flow method for 3-D images(This is an implementation of Lucas-Kanade optical flow method for three dimensional images like NIFTI, DICOM etc. A demo with test dataset is given.)

为实现合成孔径雷达（SAR）图像分类算法的测试与评估，将VC/Matlab 混合编程技术应用到SAR 图像分类平台开发中，分析与 比较了4 种VC/Matlab 混合编程方法及各自优缺点，并着重研究了基于组件对象模型（COM）的VC/Matlab 混合编程方法。使用Matlab COM 编译器创建了SAR 图像分类算法组件，在VC 中调用其导出的接口函数。在此基础上，完成了SAR 图像分类平台的实例开发且 可脱离Matlab 环境运行。实验结果表明，该方法较好地发挥了VC 与Matlab 各自的优势，提高了SAR 图像分类平台开发的效率。(In order to test synthetic aperture radar （SAR） image classification algorithm，VC/Matlab mixed programming technology was used in SAR image classification platform development. Four VC/Matlab mixed programming methods were introduced and analyzed. Comparing with other three methods，the method based on component object model （COM） was studied particularly. SAR image classification algorithm component was created by Matlab COM complier，and its interface function could be invocated with VC. Using this method，a SAR image classification platform was realized. The platform could run without Matlab. The experimental result shows a good combination of VC and Matlab. So，developing efficiency could be enhanced a lot.)

雷达回波信号分析，对于雷达方向专业的初学者有借鉴经验，程序可读性比较好。(It useful for the new learner)

本人编写的用直方图提取纹理特征的源码，希望对大家有用(I am prepared to use the histogram of the source texture feature extraction, in the hope that useful)

最近总是在这下程序，觉得也应该贡献一下，分数阶傅立叶变换的一个matlab程序(Always under the most recent in this process, feel that we should contribute about fractional Fourier transform of a matlab program)

蒙特卡洛方法的应用算例，采用matlab编写，简单实用(Monte Carlo methods of numerical example, the use of matlab to prepare, simple and practical)

结构 体 在matlab环境下的表示方法.(how to describe a structure in matlab)

kernel-ica package is a Matlab program that implements the Kernel ICA algorithm for independent component analysis (ICA). The Kernel ICA algorithm is based on the minimization of a contrast function based on kernel ideas.

I have thoroughly study the basic of image compression techniques. From that I have selected SPIHT algorithm for my research work. I have implemented on image compression for gray images using SPIHT algorithm. Image compression is implemented using this algorithm has better result over the previous result on gray images and also improved PSNR value high but on other side low result on compression ratio.
