✦ Synopsis


A tabu search algorithm is proposed for the codebook generation in vector quantization. The key question is the definition of neighboring solution. Making random modifications to the current solution alone is not sufficient. The proposed algorithm first makes non-local changes to the codebook which is then fine-tuned by the generalized Lloyd algorithm (GLA). For a set of gray-scale images, the new algorithm was better than GLA alone, and its results were comparable to simulated annealing. For binary images, the tabu search approach gave the best MSE-values.

In this paper, a novel encoding algorithm for vector quantization is presented. Our method uses a set of transformed codewords and partial distortion rejection to determine the reproduction vector of an input vector. Experimental results show that our algorithm is superior to other methods in terms

## Abstract One of the major difficulties arising in vector quantization (VQ) is high encoding time complexity. Based on the well‐known partial distance search (PDS) method and a special order of codewords in VQ codebook, two simple and efficient methods are introduced in fast full search vector qu
