m.file frequency filter for image processing applications

这是一个正交交叉的量子行为粒子群算法的matlab程序（MOQPSO）,用户可以根据需求自己更换目标函数(this is an multi-collapse Orthogonal cross quantum-behaved particle swarm optimization program of matlab，the user can revise the Object function for your need.)

说明：  基于线性约束最小方差（LCMV）准则、ASC旁瓣相消——MSE准则的波束合成，运行效果极好，放心下载。(Based on the linear constrained minimum variance (LCMV) criterion, ASC Sidelobe Canceller- MSE criterion beamformer, run very effective, secure download.)

基于SIFT的图像配准，使用的是matlab自带函数(SIFT-based image registration, using its own function matlab)

(1) 产生数值为±1的用户随机数据；给出Matlab下对应的模块； (2) 产生并给出64×64的Walsh矩阵，作为用户接入的扩频码； (3) 利用上述一个用户的扩频码和用户数据演示扩频过程；给出Simulink工作框图； (4) 利用FFT，计算并画出基带数据和扩频信号的频谱（在一个图中给出）； ((1) value of ± 1 generated random data users given under the corresponding Matlab module (2) generation and gives the Walsh 64 × 64 matrix, as the user access to the spreading code (3) the use of the a user' s spreading code and spread spectrum user data presentation process given work Simulink block diagram (4) the use of FFT, calculate and draw the base-band spectrum data and the spread spectrum signal (given in a diagram) )

这个文件可以用来更改matlab生成的界面的标题栏的小山似的图标，换为自己自定义的任何图片(This document can be used to generate matlab change the title bar of the interface of the hill-like icon for their own self-definition for any picture)
