Ppt A Fast Lbg Codebook Training Algorithm For Vector Quantization Abstract: the paper presents a fast codebook training algorithm for vector quantisation. Our efforts are to design a fast algorithm to generate a better codebook and to reduce the computation time compared with the previous algorithms in codebook generation. our algorithm is a top down algorithm and is based on the longest distance first concept. In his paper wepresent a new theoretical approach to the problem of optimal vector quantization. we base, infact, ourmethod on the apriori explicit analysis of the effects onthe mse distortion introduced by an arbitrary exchange of training vectors among clusters. By checking the stability of codewords, the status of each codeword in the codebook can be de termined. only the unstable codewords are refined to generate the new codebook. the proposed method can be further improved by cooperating with the finite state technique.

By implementing a fast search algorithm named mfaupi (modified fast algorithm using projection and inequality) for vq encoding in the partition step of cgaucd, the codebook generation time can be further reduced significantly. Abstract: the authors point out that the lbg algorithm (see y. linde et al., (1980)) requires a lot of computation as the training vectors increase, and proposes a fast vq (vector quantization) algorithm for a large amount of training data. A new fast search algorithm for vector quantization has been proposed. the algorithm uses 1) the knowledge about distances and angles between input and code vectors and 2) a third con stant vector to reduce the codeword searching area. Abstract—in this paper, we propose two fast and efficient methods to generate codebook for vector quantization (vq). the computational complexity is very simple when compared to any one of the existing algorithms for generating codebook for vq.
