摘    要:本文在学习矢量量化和模糊矢量量化算法的基础上,设计了一种新的训练矢量超球体收缩方案和码书学习公式,提出了一种快速模糊矢量量化算法。该算法具有对初始码书选取信赖性小,不会陷入局部最小和运算最小的优点。实验表明,FFVQ设计的图像码书性能与FVA算法相比,训练时间大大缩短,峰值信噪比也有改善。

关 键 词:图像编码  学习矢量量化  模糊矢量量化

Abstract:In this paper,we design a new approach of the training vector hypersphere shrinking and codebook learning formula,and present a fast fuzzy vector quantization algorithm (FFVQ) based on the learning vector quantization (LVQ) and fuzzy vector quantization (FVQ) technique.It can reduce the dependence of resulting codebook on the initial codebook selection,is not trapped in local minimum and has low operational complexity.Simulation results show that as the image coding performance of FFVQ is compared with that of FVQ,the training time is reduced more,and the PSNR value is also improved.
Keywords:Image coding  Learning vector quantization  Fuzzy vector quantization
