新的小波去噪程序
- 通过分析硬阈值函数的数学特性,并考察其对电能质量扰动信号的去噪过程可知, 该算法仅简单的对小波系数进行剔除与保留,在抑制噪声的同时也容易将突变点去除, 最终导致扰动定位失效,不利于分析电网故障的类型以及发生的起止时刻。(By analyzing the mathematical characteristics of the hard threshold function and investigating its denoising process to the power quality
新建文件夹 (5)
- 基于MATLAB的狄克逊和拉伊达准则,可用于判断和剔除粗大误差和野值(The Dixon criterion based on MATLAB can be used to judge gross errors and outliers.)
Wild value rejection
- 此程序采用四种常见的准则进行粗差的剔除。(This program uses four common criteria for the elimination of outliers.)
Ransac拟合直线和圆
- C# 实现直线拟合,圆拟合 ransac算法,剔除忽略点(C# realizes line fitting and circle fitting with ransac algorithm to eliminate the ignored points)
MonteCarlo
- 是用于解决剔除样本异常值的蒙特卡洛mtlab代码,可以进行参考(Monte Carlo matlab code)
TDCS
- 变换域通信系统通过在收发端,对环境进行频谱采样,剔除干扰频段,生成不含干扰的基本调制波形用于信息调制。(Transform domain communication system)
Denoisewp
- 运用小波包分解功能对含噪信号降噪,剔除干扰噪声,提高信号信噪比。(The function of wavelet packet decomposition is used to denoise the noisy signal, eliminate the interference noise and improve the signal-to-noise ratio.)
SURF
- 程序由matlab编制,用于视觉目标图像surf特征提取和特征匹配及误匹配特征的剔除(good for feature matching)
