这是一个将指定区域内的图像提取出来，与指定图像进行融合的matlab程序，由泊松方程引申而来(This is a designated area of the extracted image, with a specified image of Matlab integration process from the Poisson equation arising from)

根据干扰信号波形样式的不同，压制性干扰可分为噪声调幅干扰、噪声调频干扰、噪声调相干扰。就是用噪声或类似噪声的干扰信号遮盖或淹没有用信号，阻止雷达检测目标信息。它的基本原理是：任何一部雷达都有外部噪声和内部噪声，雷达对目标的检测是在这些噪声中进行的，其检测又是基于一定的概率准则的。一般来说，如果目标信号能量S与噪声能量N相比（信噪比S/N），超过检测门限D，则可以保证一定的虚警概率Pfa的条件下达到可检测目标回波所要求的检测概率Pd，简称为可发现目标，否则便称为不可发现目标。(Blanket Jamming can be divided into different styles according to the interference signal waveform, noise AM interference, noise FM jamming noise phase modulation interference. With noise or noise-like interference signal covered or submerged useful signal prevent radar detection target information from. Its basic principle is: any one radar has the external noise and the internal noise of the radar target detection in these noise detection is based on a certain probability criterion. Generally, compared to if the target signal energy S and noise energy N (signal-to-noise ratio S/N), more than the detection threshold D, you can guarantee reach target echo can be detected under the conditions of a certain false alarm probability Pfa requirements detection probability Pd, referred to can be found in the target, otherwise known as not finding the target.)

matlab高级讲义，里面涵盖了MATLAB的几乎所有需要用到的模块。(matlab senior notes, which covers almost all MATLAB needed module.)

特别牛的SIFT实现，VLFeat 0.9.13，代码特别清晰。C语言编写，有matlab接口。还包括了SIFT, MSER, k-means, hierarchical k-means等相关算法。(A library implements popular computer vision algorithms including SIFT, MSER, k-means, hierarchical k-means. )
