Tsai标定方法的matlab实现，送给喜欢用matlab编程的朋友！-the methods of Tsai calibration using malab

一个计算机图形算法演示程序，对计算机图形算法的具体实现进行了编写。可做为学习图形算法的参考！-a computer graphics algorithms demo program, computer graphics algorithms to a concrete realization of the preparation. Graphics can serve as learning algorithm reference!

此代码作为图像处理中进行ＦＦＴ变换，该代码进行128*128，256*256，512*512矩阵的图像变换。-such as image processing code for FFT transform, the code 128* 128. 256* 256* 512 matrix of image transformation.

读取TM波段3和波段4的图像，计算归一化植被指数NDVI，并用NDVI处理单波段图像，突出显示遥感影像的植被部分（输出后的图像上高亮的部分是植被区域）-Band 3 and band 4 images of a TM image are read and NDVI computed. Then a single band image is processed with the NDVI leading to the vegetation regions in the remote sensed image are highlighted(the hightlighted areas in the output image are vegetation regions).

It is a magic picture.

应用DC绘图的实例，简洁明了适合初学者参考；同时又ButtonST的应用。-Examples of application of DC mapping, concise reference for beginners and ButtonST applications.

纯C写的BMP图象处理代码。做底层图象处理有用啊-write pure C BMP image processing code. So the bottom image processing useful ah
