图像处理功能：求the MSE/SNR/PSNR and the quantized image- the MSE/SNR/PSNR and the quantized image

该代码用于给出在matlab环境下求峰值信噪比及比特率。-The matlab code for the given environment in order to peak signal to noise ratio and bit rate.

本文件利用matlab对图像进行scalar quantization。程序分别对图像进行了8，16，32，64level量化，同时计算出了不同level的MSE/SNR/PSNR 。-This matlab file realize the scalar quantization on the image. The program quantizes the image with 8, 16, 32, 64 levels respec

图像处理中的量化方法以及MSE/SNR/PSNR误差计算，采用了Level=16和Level=8两种量化方式。-Quantitative methods in image processing and MSE/SNR/PSNR error calculation, Level = 16 Level = 8 two quantitative methods.
