idl环境下运行，计算两幅图像的交叉相关系数，用于变化检测方面的研究-idl environment to run the calculation two images of cross-correlation coefficient for change detection studies

这个程序包里面包含读取遥感影像的IDL代码，可以读取多个波段，并且显示图像！-This package which contains the IDL remote sensing image to read the code, which can be read by a number of bands, and display images!

该代码采用IDL语言实现了从光谱库读取高光谱曲线，并且去除其包络。这是高光谱图像处理时一个重要的预处理技术。-The code using IDL language library to read from the spectrum of high spectral curve, and the removal of the envelope. It is time hyperspectral image processing is an important pre-processing tec

IDL的实习，对图像进行处理，图像均衡化，图像平滑，缩放等功能-with this ,we can deal with picture,and we can prove our skill use IDL
