huffman编码，经测试绝对能用，大家一起分享(huffman)

说明：  SAR雷达成像的一种基本方法，距离多普勒域的RD算法(One of the SAR imaging algorithms,RD algorithm )

基于matlab的彩色图像分割，方法是K-means聚类分割(Matlab-based color image segmentation method is K-means clustering segmentation)

This is the explanation about the data encryption, and this can be mostly used in the stegnography and cryptography, This encrypts the data such as image or any data file and can be used in hiding.

this codes are about dip

QPSK波形及其经过带宽为4hz的带通滤波器(QPSK waveform and its after 4HZ bandwidth of the bandpass filter)

ICA用于雷达信号分选，基于独立分量分析的matlab程序设计。(ICA for radar signal sorting, based on independent component analysis matlab program design.)

这是一个三水源新安江模型，主要用于湿润半湿润地区流域水文预报，适合从事水文、水资源方面的朋友使用。(Xin
anjiang model hydrology model di gital watershed hydrological forecasting hydrological calculation)

The first scheme is based on the spatial locality of feature vectors corresponding to similar images. Learning is effected by modifying the query vector to incorporate the positive examples. The second scheme is based on “distorting” our view of the feature space. An new similarity distance between an image and the query is learned from the relevance feedback.
