i4_choose

Simple but effective example of "Region Growing" from a single seed point. The region is iteratively grown by comparing all unallocated neighbouring pixels to the region. The difference between a pixel s intensity value and the region s mean, is used as a measure of similarity. The pixel with the smallest difference measured this way is allocated to the region. This process stops when the intensity difference between region mean and new pixel becomes larger than a certain treshold

1、 降噪步骤： （1） 一维信号的小波分解。选择一个小波并确定分解的层次，然后进行分解运算。 （2） 小波分解高频系数的阈值量化。对各个分解尺度下得高频系数选择阈值进行软阈值量化处理。 （3） 一维小波重构。根据小波分解的最底层低频系数和各高频系数进行一维小波重构。 matlab里面有关于去噪的函数，你可以找一下~~ 这说的只是基本原理，希望有所帮助(1, noise reduction steps: (1) one-dimensional signal wavelet decomposition. Select a wavelet decomposition level and determining, and then divide the operation. (2) high coefficient wavelet thresholding. For each decomposition scales have high coefficient selection threshold soft threshold quantization. (3) one-dimensional wavelet reconstruction. According to the lowest level of the low frequency wavelet coefficients and high frequency coefficients of each one-dimensional wavelet reconstruction. There are about denoising matlab function, you can find some ~ ~ This says just the basic principle, we hope to help)

MATLAB编写利用牛拉迭代法求解简单电力系统潮流。程序可以分别运用真实值和标幺值计算，可以区分有无变压器计算。程序开始时需要输入节点数量、互联节点之间线路的阻抗等初始化参数，运行可得潮流结果，详见程序内注释。(Written in MATLAB to solve simple oxen pulling power flow using an iterative method. The program can use the true value, respectively, and the per-unit value calculation, you can distinguish whether the transformer calculations. When the program begins to enter initialization parameters such as impedance between the number of nodes, interconnected nodes lines running trend results can be obtained, the detailed program notes.)

说的是一个关于MATLAB使用的简单介绍的文件,对初学着还是有一顶帮助的(That is a study on the use MATLAB a brief document, on a beginner or a help)
