关于soft matting的MATLAB代码(A closed form solution to Natural Image Matting A. Levin D. Lischinski and Y. Weiss )

精通MATLAB7.0,是一本很好的学习MATLAB的书籍.(Proficient MATLAB7.0, are a very good study MATLAB books.)

对录音信号集 中的某一语音，利用BATLAB设计一美尔例谱算法，并实现。 取信号集 中的一个语音信号：“xxxxxx”，将它作为输入的语音信号来为设计一个美尔倒谱算法，在该算法中，主要设计了以下环节： 1.读入一个语音信号；2.对这个信号归一化；3.对归一化的信号进行加窗处理（这里的矩形窗长度必须为257，重帧长64）；4.进行预加重处理，即通过一个高通滤波器： ；5进行512点的FFT；6.分别取模平方得到功率谱；7.在设计的mel滤波器组中，我采用了25个带通滤波器；8.将得到的功率谱信号通过mel滤波器组，得到相应的25个功率值；9.对这些功率值取自然对数；10.对这些值取离散作弦变换；11.将得到的值去掉直流分量，取其它值作为MFCC参数。 (Concentrated on recording a voice signal, using BATLAB designed Mayer cases spectral algorithm, and implementation. Get a voice signal signal focus: "xxxxxx", will it as input for the design of a voice signal to Mel Cepstrum algorithm in the algorithm, the main design of the following links: 1. Read a speech signal 2. On the signal normalized 3. Of the normalized windowed signal processing (here, rectangular window length must be 257, re-frame size 64) 4. For Pre-emphasis processing through a high-pass filter: 5 for 512 points of FFT 6. modulo square were obtained spectrum 7. in the design of mel filter banks, I use a 25 band-pass filter 8 . will be the power spectrum signal by mel filter bank, corresponding to the 25 power values 9. on the power to take the natural logarithm value 10. to take these values as strings of discrete transform 11. will be of value to out DC component, to take other values as MFCC parameters.)

说明：  matlab实现维纳自适应滤波，适合初学者了解维纳自适应滤波，，大家支持我啊(Wiener adaptive filtering matlab implementation, suitable for beginners to understand adaptive Wiener filter, we support me ah)

有关曲线拟合以及解方程组的方法，及其相关指令(About fitting and solve equations)

Multivariate Relevance Vector Machines

说明：  这是一个计算图像中的欧拉数的程序.先将图像二值化,然后再求反计算欧拉数(This is a calculated image of the Euler number of procedures. First two binary images, and then calculated for anti-Euler number)
