一种彩色图像增强方法，它用于增强图像的对比度，优化图像视觉效果，同时保持几乎一致的图像色彩保真度.-A color image enhancement method, which used to enhance image contrast, optimizing the image visual effects, while maintaining almost the same image color fidelity.

求取图像信噪比 均方差 峰值信噪比 逼真度等的matlab 程序函数-Average Absolute Difference，Signal to Noise Ratio (dB)，Peak Signal to Noise Ratio (dB)，Image Fidelity，Mean Square Error，The difference between restoredimg entroy and originalimg，entroy

图像评价的几个标准，包括峰值信噪比，均方误差，平均绝对误差，图像保真度，信噪比的MATLAB代码，采用基本编程方法，适合初学者加深图像客观评价标准的理解。-Image evaluation of several criteria, including PSNR, MSE, mean absolute error, image fidelity, signal to noise ratio of the MATLAB code, using the basic programming for be

本实验要求编写一个计算压缩-解压缩图像的均方根误差、均方信噪比的程序。该程序是一个通用程序。编写程序产生图示的结果。使用上面的保真度准则程序计算可视信息的损失特性。-Prepared in this experiment, a calculation of compression- decompression of the root-mean-square error of image, mean square signal to noise ratio of the procedure. Th

Denoising Reduces the total-variation of the image. Filters out noise while preserving edges. Textures and fine-scale details are also removed. In this demo the assumption is that a white Gaussian noise is added with priori known (or estimated) noi
