ImageFiltering

本程序对OFDM这一调制方式的基本流程进行了仿真，通过高斯白噪声信道，接收信号解调，对比发送和接收信号波形，并画出功率谱密度图形(This program OFDM modulation scheme of this basic flow of the simulation carried out by white Gaussian noise channel, the received signal demodulation, compare sent and received signal waveforms and power spectral density plot graphics)

说明：  拉丁超立方，去抽取样本，是一种从多元参数分布中近似随机抽样的方法，属于分层抽样技术，常用于计算机实验或蒙特卡洛积分等。(Latin hypercube sampling)

说明：  多目标遗传算法二代，可直接使用，内有详细说明(NSGA_2,can be used directly,which is explained in detail)

说明：  matlab模拟透镜的初级相差,求出其初级相差。(matlab )

基于信息熵的免疫算法，是人工免疫算法的改进研究，用Matlab编写(Immune algorithm based on information entropy, to improve the research of artificial immune algorithm, written using Matlab)

奥本海姆的《信号与系统》教材第二版中文版 适合初学信号与系统哦~(Oppenheim Signals and Systems " textbook second edition of the Chinese version suitable for beginners Signals and Systems oh)

主要使图像进行灰度化处理，matlab的源代码，视同再进一步的预处理中应用(Gray image)

说明：  经典的SIFT算法，第一步，选择感兴趣的点；第二步，对感兴趣点进行筛选，确定关键点；第三步，为关键点分配方向；第四步，用多维向量的形式描述关键点(Classical SIFT algorithm, the first step, select the point of interest second step, points of interest were screened to identify key points the third step, the key point for the distribution of direction The fourth step is described with the key in the form of multi-dimensional vector point)
