knn分类器，是数字图像处理与处理中经常使用到的一种分类方法！(KNN Classifier is the digital image processing and handling are often used as a classification method!)

说明：  自己编写的图像质量评价函数，包括方差、平均梯度、模糊熵、信息熵(I have written the image quality evaluation function, including the variance, with an average gradient, fuzzy entropy, information entropy)

二值化图像,提取图像中的圆形，例如提取照片中的车轮(Extracting a circular image, for example, extraction wheel photo)

一种有效的匹配滤波估算地层品质因子的方法，精度较高，稳定性较好，值得借鉴(A kind of effective method of matched filtering to estimate formation quality factor, high precision, good stability, is worth using for reference)

该代码是基于学习的超分辨率重建，此算法是在线字典学习，字典的训练与稀疏表示与重建同时进行。(This code is based on the study of super-resolution reconstruction, this algorithm is learning online dictionaries, dictionaries of training and sparse representation and reconstruction simultaneously.)

对图像进行边缘检测的程序，实例为经典的lena图像。(The image edge detection procedures, examples of classic lena image.)

粒子滤波重采样方法实现程序，包括随机重采样、多项式重采样、系统重采样、残差重采样程序(Particle filter resampling method procedures, including random resampling, resampling polynomial system resampling, residual resampling procedure)

说明：  一维高斯粗糙面、三维高斯粗糙面的建模，基尔霍夫近似法求散射系数(Modeling of one-dimensional Gaussian rough surface and three-dimensional Gaussian rough surface, and Kirchhoff approximation method to calculate scattering coefficient)

非精确ALM解决PCA算法的例子，用后效果不错，发上来分享。(This matlab code implements the inexact augmented Lagrange multiplier method for Robust PCA.)
