摘要
通过对子帧的矢量量化 (简称SVQ)压缩方案的分析 ,对SVQ和VQ的压缩机理和压缩特性进行了比较 ,并提出了SVQ的一些新的、有利用价值的特点 .模拟实验结果证明 ,这些特点有助于提高重建图像的信噪比 。
Through the analyses of the compression scheme, Sub-frame Vector Quantization (SVQ), we made a comparison of the compression mechanism and the characteristics between SVQ and VQ, and thus brought up some new and valuable features of SVQ. The simulation's results proved that these features would contribute much to enhancing the SNR of the reconstructed image, reducing the blocking effect and generating the codebook in much better order.
