利用IDL读取MODIS影像L1B和MOD03数据(HDF格式),计算遥感植被指数NDVI

本程序可以读取TMI传感器数据，并生成为tif格式的影像。-The program can read the the the TMI sensor data, and students become tif format images.

读取医疗影像设备图像的MATLAB程序，非常好用，简单易学-Read medical imaging equipment images MATLAB program, very easy to use, easy to learn

读取图像 \examples\data\convec.dat，并对它进行均值平滑（smooth 和median），另外利用Sobel和Roberts函数使用以下3*3的窗口对图像进行卷积。给出IDL编程代码及其运行结果。(The image \\examples\\data\\convec.dat is read, and its mean smoothing (smooth and median) is performed. In addition, Sobel and Roberts fun
