[Special Effects] MATLAB_PICTURE_PROCESSING DL : 0: 使用MATLAB，实现以下四个功能一、获取图片RGB值：给定一张图片，获取点(x,y)，以及(x,y)周围8个点的R、G、B值。二、实现rgb2gray函数：使用matlab实现rgb2gray的功能，并能计算出转换后灰度图片的方差。三、灰度图对比度增强：分别使用灰度拉伸和直方图均衡化，增强给定图的对比度。四、图像去噪：对给定图片加椒盐噪声，并选择两个去噪算法去除椒盐噪声。 -Using MATLAB, to achieve the following four functions First, access to image RGB value: Given a picture, get the point (x, y), and (x, y) around 8 o clock in the R, G, B values. Second, the realization rgb2gray function: using matlab realize rgb2gray functions, and can calculate the variance after the conversion of grayscale image. Third, the grayscale contrast enhancement: namely, the use of gray stretch and histogram equalization, contrast enhancement given graph. Fourth, the image denoising: for a given image add salt and pepper noise, and you know at least two denoising algorithm to remove salt and pepper noise.

[Special Effects] MATLAB视频去雾【GUI，源码，论文】 DL : 0: 该课题是基于MATLAB平台的图像去雾处理，配备一个人机交互GUI界面，可以选择局部直方图均衡化，全局直方图均衡化，Retinex算法，通过对比处理前、后的图像的直方图，而直方图是一副图像各灰度值在0-256的分布个数的表，信息论已经整明，具有均匀分布直方图的图像，其信息量是最大的。二、算法介绍 ①全局直方图均衡化：通俗地理解就是，不管三七二十一，直接强行对彩色图像的R,G,B三通道颜色进行histeq均衡处理，然后进行三通道重组； ②局部直方图均衡化：设置一个固定大小的滑块，分别对彩色图像进行R,G,B三通道进行逐个像素地平滑处理，然后重组三通道，当然这样做的，虽然实现了图像的去雾效果，但是以部分像素曝光作为牺牲补偿。 ③Retinex算法：通俗地讲就是，分离R,G,B三通道，对每个通道进行卷积滤波。(This project is based on MATLAB platform image defogging processing, equipped with a human-computer interactive GUI interface, you can choose local histogram equalization, global histogram equalization, Retinex algorithm, by comparing the histogram of the image before and after processing, and the histogram is a table of the number of gray value distribution in 0-256, information theory has been clear, with uniform distribution histogram Image, its information is the largest.)
