sift算子中高斯金字塔和DOG的生成，只是该算子的最初步骤(sift operator：the generation of Gaussian pyramid and DOG。it is only the first steps)

本程序为多个不同脉冲程序。用于刺激或脉冲发生器的研究(This program is different pulse program. Or pulse generator for stimulating research)

matching pursuit 算法，matlab实现，信号稀疏分解方式的一种，适合与信号在超完备的原子库中稀疏分解。matchingpursuit.m(A matching pursuit algorithm. It fits data from a set of dictionary elements by orthogonally projecting the data onto elements of the dictionary of vectors such that the energy in each projection is maximized. In constrast to G-S, the residual is orthogonalized, not the basis vectors)

Support Vector Machine Implementation in MATLAB

this matlab code reads the data text files UCI Spoken Arabic Digits and save the results in a mat file which user can easily use.

frequency expander. Matlab code for expander.When x is a vector, this function adds L-1 after each element of x. When x is a matrix, each column of it treated as vector and expanded L fold. SQUARE-ROOT RAISED-COSINE PULSE: h=sr_cos_p(N,L,alpha) This function generates a square-root raised-cosine pulse of length N+1. There are L samples per symbol period. alpha is the roll-off factor.

基于兴趣点颜色及纹理特征的图像检索算法，通过同类比较，平均检索准确率提高11个百分点。(Based on the interest points and texture features of color image retrieval algorithm, through a similar comparison, the average retrieval accuracy rate of 11 percent improve.)
