matlab code for event driven data harvesting in wsn

提供了一个扩展卡尔曼滤波源程序，无迹卡尔曼滤波源程序，交互式模型卡尔曼滤波源程序，扩展卡尔曼滤波及无迹卡尔曼滤波对比源程序及一个扩展卡尔曼滤波的目标跟踪算法源程序。(An extended kalman filter source program, no trace kalman filter source program, interactive model kalman filter source program, extended kalman filter and non trace kalman filter contrast source program and an extended kalman filter target tracking algorithm source program are provided.)

说明：  】利用混沌动力学系统中logistic 映射先对水印图像进行置乱预处理以增强其鲁棒性, 在小波域中将原始音频信号按比例分段, 此比例为原始音频信号低频部分与水印信号个数之比, 然后将水印信号加入到音频信号的 低频部分。用StirMark 攻击后的实验结果表明, 该算法对StirMark 的部分攻击具有一定的鲁棒性。(The logistic- map sequences to encrypt the watermark are used. The original audio signal in DWT (Discrete Wavelet Transform) domain is seperated into some pieces determined by the ratio between the length of the low frequency parts and the length of the encrypted watermark. Every bit of the watermark is added into the relevant pieces of the low frequency parts in the DWT domain. Experimental results show that the algorithm is robust against some StirMark attacks.)

说明：  这个是MATLAB实现Hough变换的程序。有基本的Hough变换的理解程序，也有使用Hough变换来检测信号的程序(This is the realization of Hough Transform MATLAB procedures. Hough transform a basic understanding of procedures, have also used the Hough transform to detect the signal process)

这是一个Knn分类算法的Python实现，Matlab中有类似的函数(knn classifer)

matab实现自适应lms滤波的基本程序，毕业设计专用(the basic procedures of matab adaptive LMS filter, graduation design dedicated)
