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

图像压缩主要目的是为了节省存储空间,增加传输速度。图像压缩的理想标准是信息丢失最少,压缩比例最大。不损失图像质量的压缩称为无损压缩,无损压缩不可能达到很高的压缩比;损失图像质量的压缩称为有损压缩,高的压缩比是以牺牲图像质量为代价的。压缩的实现方法是对图像重新进行编码,希望用更少的数据表示图像。-The main purpose of image compression to save storage space, increase the transmission speed. The idea
