混合像元分解，是定量遥感中非常重要的组成部分之一，在反演地表参数时是必须要考虑的因素之一，文中罗列了分解的一些方法。(mixed pixel decomposition, is the quantification of remote sensing very important component of one of the the inversion of surface parameters is to be considered one of the factors, the paper listed some of the decomposition method.)

利用MATLAB对图像边界内部的部分进行填充，以便后期对图像处理(Using MATLAB within the boundaries of the part of the image to fill, so that the latter part of the image processing)

使用IDL实现对ENVI所支持的影像文件格式的数据拼接，不用打开栅格，从而避免内存消耗过大(IDL data stitching ENVI image file formats supported, do not open the grid, in order to avoid memory consumption is too large)

本算法实现了dct基字典的构造并用其进行对图像的消噪。(Algorithm DCT-based dictionary structure and use it for image de-noising.)

灰度质心法提取图像圆点中心坐标程序源代码(Extracted gray-scale image centroid coordinates of the dot center of the source code)

说明：  图像分割，还可以，kmeans聚类的方法。k-means算法是一种聚类算法，所谓聚类，即根据相似性原则，将具有较高相似度的数据对象划分至同一类簇，将具有较高相异度的数据对象划分至不同类簇。(K-means algorithm is a clustering algorithm. The so-called clustering is to divide data objects with high similarity into the same class cluster and data objects with high dissimilarity into different class clusters according to the similarity principle.)

用哈夫曼算法对图像进行压缩， 1.颜色模式转换及采样； 2．DCT变换（离散余弦变换）； 3．量化；4．编码（有算术编码和哈夫曼编码两种，这里采用哈夫曼编码）

用C语言实现位图格式的图像读取功能，可直接使用。(read BMP by C ,can be used directly.)

说明：  国外编写的双树复小波的一个开发包，包括1维和2维的情况，文件中有说明。(The Dual-Tree Complex Wavelet prepared outside of a development package, including the one-dimensional and two-dimensional case, the document has made it clear.)

robustly fits a homography to a set of putatively matched image points(robustly fits a homography to a set of putat ively matched image points)
