第二能量熵的matlab代码

一个很好用的图像GHM多小波变换程序,实现一阶变换(a very easy function for GHM，can do first GHM transform.)

sift function in matlab

对一段wav文件读取，并做简单的降噪处理，其中包含了高通滤波器的设计。适合新手(Wav file on a read and do simple noise reduction, which contains a high-pass filter design. For novice)

说明：  根据张贤达版《现代信号处理》中几种经典的自适应滤波器算法，包括LMS, NLMS, RLS, Kalman, 解相关LMS, 以及相互进行对比，并画出对比图(Adaptive filter, LMS, NLMS, RLS, Kalman, etc.)

说明：  基于人耳识别听觉系统基础的梅尔频谱倒谱系数（MFCC），本次设计采用经过小波包阈值降噪处理的音频文件，提取出其相应的MFCC特征矩阵，以便做接下来的分析！(Based on the Mel spectrum cepstrum coefficient (MFCC) of human ear recognition and hearing system, this design uses the audio file processed by wavelet packet threshold denoising, and extracts its corresponding MFCC feature matrix for the next analysis!)

猫脸变换用于水印中，将水印图像经过一定次数的变换得到不能识别的图像，增强了水印的鲁棒性(Cat face transform for watermarking, the watermark image after a certain number of times the transform of the image does not recognize and enhance the robustness)

WSN中DOA算法的mds定位，对于DOA非常有用(DOA algorithms in WSN MDS positioning, very useful for DOA)

VB和Matlab/Simulink的接口方法(VB and Matlab/Simulink interface methods)

说明：  matlab 图像处理 使用噪声能量和图像一维自相关函数进行维纳滤波(matlab image processing and image noise energy use one-dimensional autocorrelation function of Wiener filter)

说明：  通过MATLAB7.1编写程序，对已知的图像进行解码操作(jiemi)
