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 respectively, and then compute the v

Image Compression and Watermarking scheme using Scalar Quantization

编程实现颜色标量量化。输入为24位彩色图像，将RGB分量分别保持头3位、头3位、头2位的值不变，其余各位变为10000、10000和100000，观察处理后的图像的颜色失真情况。注意OpenCV中的RGB分量的存储顺序为BGR。-Programming color scalar quantization. Enter the 24-bit color images, the RGB components respectively held the first three, the first t
