摘要
本文报道了一种新的活动图像编码算法,称为自适应多值量化的亚抽样块截断编码。模拟结果表明:这种新算法比现有的其它同类算法有更好的性能,压缩比为30,信噪比为35.4dB,图像主观质量良好,在现有个人计算机上可以用软件实时实现。
In this paper, a novel moving picture coding algorithm, called the adaptive multilevel quantized subsampled block truncation coding is presented. The experiments show that this algorithm has better performance than the other algorithms of the same kind and can be realized in real time with software in current PC, the compression ratio is 30 and the peak signal to noise ratio is 35.4 dB.
