在matlab中实现模式识别中的一个分类器——fisher分类器(Pattern recognition in matlab to implement a classifier- fisher classifier)

说明：  （1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象； （2）将所有子图象按列相接变成一个81维的行向量； （3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量； （4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。 （5）求出所有子块的特征向量。 ((1) the application of 9 × 9 window of these images at random, a total sample of 200 sub-image (2) all sub-images according to out-phase into a 81-dimensional row vector (3) all 200 lines for KL transform vector, derived its corresponding covariance matrix of eigenvectors and eigenvalues, in descending order by eigenvalue and the corresponding eigenvector (4) a choice to 40 corresponding to the largest eigenvalue eigenvector as the PCA, the original image block to the 40 feature vectors on the projection, the projection coefficients obtained by this sub-block eigenvector. (5) calculated for all sub-block eigenvector.)

关于蒙特卡洛法进行计算面积的，根据随机投点所得到的频率反推概率来求得面积。很好用的一种思维方法(About the Monte Carlo method to calculate the area, according to the random frequency of investment points to get the probability to obtain the inverse area. A good way of thinking with)

用于结构优化的粒子群算法，计算速度较快，目前较优秀的算法(Particle swarm optimization algorithm used to calculate faster than the best current algorithm)

说明：  用于图像拼接，图像序列的柱面全景拼接算法，matlab仿真程序(For image mosaic, image sequence cylindrical panorama stitching algorithm, matlab simulation program)

selection combining模式下，瑞利信道下的能量检测(the Selection Combining mode, Rayleigh channel energy detection)

breaks up an array into a cell array of adjacent sub-arrays of equal sizes

说明：  hand-written RBF code for predicting
