时间序列分析，分析序列是否是 白色噪声，分析相关性，可以进一步判断序列的相关和自相关-time series analysis, whether the sequence is white noise, correlation analysis, further sequence of judgment and autocorrelation

该程序比较人性化，有个友好界面，能加载图像，并根据图像训练Hopfield神经网络，你也可以通过添加噪声给图像，以判断它的识别率。

基于噪声检测的中值滤波，先通过邻域计算检测是否为噪声，再进行开关中值滤波，对于被判断为噪声的像素不再参与其他像素的中值滤波，能够有效滤除噪声并且保留细节较好-Noise Detection Based on median filtering, first calculated by testing whether the neighborhood noise, then the switching median filter for noise pixels are judged to no l
