说明：  图像特征提取的四种算法，花了很大的力气才弄来的！和大家分享！(Four types of image feature extraction algorithm, to spend a great deal of effort to get the! To share with you all!)

数字图像处理，图像质量评价指标，matlab 计算图像峰值信噪比(Calculation of peak signal to noise ratio)

otsu s multilevel thresholding method

此文档中的代码可以计算5种图像的质量参数，分别是：图像灰度均值、图像方差、图像平均梯度、熵和峰值信噪比及均方误差。(The code in this document can be calculated five kinds of image quality parameters, namely: the image gray value, image variance, average gradient image, entropy and peak signal to noise ratio and mean square error.)

RMSHE and AMSHE 可直接运行的直方图增强算法，附有相关的论文(RMSHE and AMSHE can be directly run by histogram enhancement algorithm, with related papers.)

陆文凯老师数字图像处理第二次作业，前景背景分割和前景区域面积计算(Wen-Kai Lu a teacher of digital image processing a second operation, the background segmentation and the prospects for the future size of the area calculation)

说明：  经典的大津otsu算法在matlab中的实现程序，每一步都是经典步骤。(Otsu classical Otsus algorithm in matlab implementation process, each step is the classical steps.)

CV模型水平集代码，包括图片、代码和运行结果(The level set evolution function of the CV model)

灰度数字图像增强处理,灰度数字图像增强处理,灰度数字图像增强处理,(Deal with gray-scale digital image enhancement)

在使用envi中的band_math时需要将两张图像设置为相同的行和列，改程序解决了该问题(In use of envi band_math need two images set to the same rows and columns, change the program to solve the problem)
