基于matlab的简单函数优化的遗传算法程序(genetic algorithm )

SURF Features A frequent approach to feature extraction from images is SURF (Speeded Up Robust Features) Codebook You can use the function create_codebook.m to create a codebook with k-means Histograms Write a function that creates histograms of single images by assigning the image features to clusters from the codebook and counting their frequency Object recognition Choose two distinct subsets from the images. Create a codebook from one set

利用粗糙集实现对数据的清洗，清洗掉无效的数据(he use of rough set to achieve the data cleaning, cleaning out invalid data)

说明：  序列x（n）的间接法功率频估计用matlab来实现(sequence x (n) the indirect method of power frequency estimates using Matlab to achieve)

将彩色图像从RGB空间转换到YCbCr空间、HSI空间(It converts from RGB corlor space to YCbCr space.)

DVR SIMULATION ON MATLAB VERY USEFUL

MATLAB中关于三相V_I测量装置的简介与使用方法的中文介绍，和MATLAB中帮助的内容相对应(MATLAB concerning the introduction and use of the three-phase V_I measuring apparatus Chinese description, and MATLAB Help content corresponds)

利用随机序列进行间隔控制，选择消息隐藏位(Intervals using random sequence control, select the message hidden bits)

对周围相邻的 8 邻居求和（元胞只有两种状态，0 或 1 ）。元胞也有一个单独的状态参量（所谓 记录 ）记录它们之前是否有非零状态的邻居。 在 0 与 1 之间产生一个随机数 r 。 如果总和> 0 （至少一个邻居）并且 r >阈值，或者元胞从未有过一个邻居，则元胞= 1 。 如果总和> 0 则设置"记录"的标志，记录这些元胞有一个非零的邻居。 (8 adjacent neighbors on the surrounding sum (cell only two states, 0 or 1). Cell also has a separate state parameters (so-called ' records' ) record that they have non-zero state before the neighbors. Between 0 and 1 generate a random number r. If the sum of> 0 (at least one neighbor) and r> threshold, or the cell has never had a neighbor, then cell = 1. If the sum> 0 set the " record" sign, record the cell has a non-zero neighbors.)

This is a simple sample of crypto
