一个2维的Gabor滤波器代码，希望对大家有所帮助(a 2-D gabor filter code,I hope it helpfull for other people.)

上串文件所需的子函数，设计所需的滤波器。(a subroutine to generate filters need by bpsk,etc.)

MATLAB function which creates a black and white version of a grayscale image by specifying a single threshold value pixels below this value become black, and above this value they are white. Usage:

本程序主要通过仿真动态显示均匀平面电磁波中，磁场 Hz 的波阵面在自由空间（理想介质）中的传播。(The program primarily through dynamic simulation shows uniform plane wave, the magnetic field Hz wavefront in free space (ideal medium) in the transmission.)

该程序实现的事BPSK信号在两种信道下的仿真，分别是瑞利信道和高斯信道下的仿真，并对结果进行分析(The program implements thing BPSK signal two channel simulation, namely Rayleigh channel and Gaussian channel simulation, and the results were analyzed)

KMEANSK Performs K-means clustering given a list of feature vectors and k The argument k indicates the number of clusters you want the data to be divided into. data_vecs (N*R) is the set of R dimensional feature vectors for N data points. Each row in data_vecs gives the R dimensional vector for a single data point. Each column in data_vecs refers to values for a particular feature vector for all the N data points. The output data_idxs is a N*1 vector of integers telling which cluster number a particular data point belongs to. It also outputs centroids which is a k*R matrix, where each rows gives the vector for the cluster center. If we want to segment a color image i into 5 clusters using spacial and color information, we can use this function as follows:
