信道容量的迭代算法,使信道能够无失真地传输信源数据(Channel capacity iterative algorithm,so that the channel can be transmitted without distortion source data)

njw谱聚类算法，读者可以参考用于科研用途，其中的参数需要自己设定(spectral clustering algorithm of NJW)

源代码在matlab实现相邻帧间差分法对于视频中对移动目标的识别。附送视频，在matlab上能打开的视频只有无压缩的AVI视频。视频背景没有变化的情况下，处理效果很好。(The source code in matlab between adjacent frame difference method for the recognition of moving target in the video. Attached to the video, can open the video on the matlab only compressed AVI video. Does not change the background of video cases, the treatment effect is very good.)

This is my simulation of PMSM. Hope you can edit and use it to your exercise. It is not actually correct but I think it will be useful for you.

信息融合中的许多数据关联算法计算量大, 工程中难以保证实时性和有效性。本文就这一方面展开研究, 给出了可以满足工程实际需要的有效算法, 设计出相应的系统。通过实际系统应用, 可以获得满意的融合结果和较快的计算速度。(The comput ation quant ity of many data correlation algorithm is great in the information fusion. It is difficult to guarantee the computing speed and the validity in real time processing. By studying on this hand, this article launches the research, produces the effective algorithm suit to real engineering. The corresponding system is designed. Through the actual system application, the satisfaction the fusion result and a quicker comput ation speed is obtained.)

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.)
