Decompose image into subbands, denoise using BLS-GSM method, and recompose again. fh = decomp_reconst(im,Nsc,filter,block,noise,parent,covariance,optim,sig) im: image Nsc: number of scales filter: type of filter used (see namedFilters) block: 2x1 vector indicating the dimensions (rows and columns) of the spatial neighborhood noise: signal with the same autocorrelation as the noise parent: include (1) or not (0) a coefficient from the immediately coarser scale in the neighborhood covariance: are we considering covariance or just variance? optim: for choosing between BLS-GSM (optim = 1) and MAP-GSM (optim = 0) sig: standard deviation (scalar for uniform noise or matrix for spatially varying noise) Version using a critically sampled pyramid (orthogonal wavelet), as implemented in MatlabPyrTools (Eero).

形态学中的腐蚀和膨胀运算。首先，对图像进行低通滤波，消除细小噪声的干扰。 在滤波时，没有采用传统的中值滤波器，而是采用顺序统计滤波器ordfilt2(Erosion and dilation operation in morphology. Firstly, the image is filtered by low pass filtering to eliminate the interference of small noise. In filtering, the traditional median filter is not used, but the order statistics filter ordfilt2)

简要的Gauss列主元消去法，很实用，用matlab实现，还有一个图例，程序说明很详细(brief Gauss main-element elimination, very practical, using Matlab to achieve, there is a legend, a very detailed description of the procedures)

从物理的角度看，音乐是不同频率，不同时长声波的组合，声波的频率表示不同的音调，声波的时长反映不同的节奏，根据该原理，将不同频率，不同时长的声波进行有序组合，则能成为音乐，利用MATLAB对不同频路信号的组合及分析功能，能够进行简单的音乐合成。(From a physical point of view, the music is different frequencies, not at the same time the combination of the long acoustic wave, the frequency of the acoustic wave which means that a different tone, sound waves reflect the length of time the type of rhythm, based on the principle of different frequencies, not at the same time long waves are conducted orderly composition, to become the music, using MATLAB combination of signals of different frequencies Road and analysis capabilities, able to perform simple music synthesizer.)
