基于小波的多聚焦图像融合，使用了MATLAB语言(Image fusion by wavelet )

制作的时钟，反映实时时间。 欢迎指正。谢谢(Production of the clock, reflecting the real time.)

迫零和最小均方误差比较，非常好的程序，保证可以仿真出图形(DIP text book kmeans image segmentation Input: ima: grey color image k: Number of classes Output: mu: vector of class means mask:)

对K-means聚类算法的改进X-means算法。针对K值如何设定的问题，利用BIC准则判断聚类点数量。同时附有两个初始聚类点的选择程序，自己选吧。(The improved X-means algorithm for K-means clustering algorithm. In view of the problem of how to set the K value, the number of clustering points is judged by the BIC criterion. At the same time, there are two initial clustering points of the selection program, choose it yourself.)

jille model The performance of the method is evaluated by experimental data. Jiles-Atherton model with five parameters describes the hysteresis behavior of ferromagnetic materials.

正交相移键控 (Quadrature Phase Shift Keying)简称“QPSK”，是一种数字调制方式。它分为绝对相移和相对相移两种。由于绝对相移方式存在相位模糊问题，所以在实际中主要采用相对移相方式DQPSK。目前已经广泛应用于无线通信中，成为现代通信中一种十分重要的调制解调方式。(QPSK THAT IS TO SAY....)

说明：  根据掺镱光纤激光器的速率方程，对激光器工作进行仿真(According to the ytterbium doped fiber laser rate equations，simulate the laser‘s working)
