多类 kmeans 图像分割，基于灰度的图像分割。(Kmeans image segmentation, segmentation based on gray-scale images.)

说明：  一种图像阈值分割算法。能够对图像.sauvola是一种考虑局部均值亮度的图像二值化方法, 以局部均值为基准在根据标准差做些微调.算法实现上一般用积分图方法来实现.这个方法能很好的解决全局阈值方法的短板—关照不均图像二值化不好的问题.(Image threshold segmentation algorithm)

本程序可以实现对图像的中值滤波，从而除去图像中的某些干扰(This procedure can be achieved on the image median filter, thereby removing some of the interference image)

实现基本的LMS算法和归一化LMS算法学习曲线的比较仿真(LMS algorithm and normalized LMS algorithm learning curve comparing simulation)

用于图像中边缘检测的重要算法，radon变换，该MATLAB程序实现了radon变换，直接确定图像中边缘位置和边缘强度(Radon convert)

该代码为用tamura算法提取图像的纹理特征，包括粗糙度、对比度等，可用于基于内容的图像检索系统(The code for the algorithm used tamura extracted texture features, including roughness, contrast, etc., can be used for content-based image retrieval system)

* 说明: 该函数将对图象进行（成对函数匹配）操作。需要注意的是，此程序先要求对图像进行特征提取及形态学操作等，使其成为二值图像。(* Note: This function will be images (paired function matching) operation. Note that this procedure require image feature extraction and morphological operations, making it a binary image.)

Solutions to problems in the field of digital image processing generally require extensive experimental work involving software simulation and testing with large sets of sample images.

基于非局部图像去噪模型的遥感图像融合的变分方法。该变分方法采用梯度下降法。(Variational method of remote sensing images nonlocal image denoising model fusion. The variational method using gradient descent.)

傅立叶变换，等距离采样，等角度采样，轮廓提取，形态处理(Fourier transform, equidistant sampling, in terms of sampling, contour extraction, morphological processing)
