Fast VQ Codebook Search in KLT Space
An acceleration technique of codebook search in vector quantization (VQ) is proposed. The algorithm works in Karhunen Loeve Transform (KLT) space. It is based on partial distortion elimination and projection on two principal components. Its performance is about 20% better than equal mean, equal variance algorithm (EMV).
متن کاملFast VQ codebook search algorithm for grayscale image coding
In this paper, a fast codebook search algorithm that is equivalent to the full search algorithm for image vector quantization is proposed. The image encoding procedure of VQ needs to find the closest codewords in the codebook for image blocks. A great deal of computational cost is consumed in the image encoding procedure. The proposed algorithm employs two test conditions to speedup the image e...
متن کاملA Fast Partial Distance Search Algorithm for VQ Codebook
Vector quantization (VQ) is an efficient technique for image compression. However, one of the most serious problems of VQ is the heavily computational load for searching the closest codeword to the input vector in the codebook. To overcome this problem, we propose a simple and fast partial distance search algorithm for VQ codebook by using the sum-norm pyramid structure of codewords. The propos...
متن کاملFast LBG codebook generator for BTC image
Conclu.sitm We proposed a simple dynamic index mapping which considerably reduces the index entropy by expoiting interhlock correlation. It was shown that it provides a considerable amount of hit-rate reduction not only in ordinary VQ but also in many hybrid VQ systems. Since the proposed index encoding scheme requires only a small amount of additional computation and does not change the quanti...
متن کاملFast codebook search algorithms based on tree-structured vector quantization
Tree-Structured Vector Quantization (TSVQ) is a highly efficient technique for locating an appropriate codeword for each input vector. The algorithm does not guarantee that the selected codeword is the closest one to the input vector. Consequently, the image quality of TSVQ is worse than that of full-search VQ (FSVQ). Although researchers have proposed multipath TSVQ and DP-TSVQ to enhance the ...
