已知两个不同图像块亮度数据如下:
(1)分析DCT原理,采用DCT方法,编程并计算相应的DCT系数,分析系数分布特点。
(2)依据视觉特性分析量化表步长的分布特点,完成DCT系数量化。
(3)采用Z形扫描,实现输出数据的统计编码,形成Video stream。
(4)采用IDCT重建图像亮度数据,计算SAD大小,分析产生误差的原因及采用DCT进行数据压缩的原理。( )
(5)分别利用左上角1、3、6个系数重建图像,计算相应的SAD,并由

The following implementation steps have been made for the devised algorithm, which is based on 2D-wavelet.
1. Reading an image of either gray scale or RGB image.
2. Converting the image into grayscale if the image is RGB.
3. Decomposition of im
