In this paper we examin the application of self-organizing list to vector quantizer for digital image coding. Owing to computational complexity and memory storage , Vector quantizer can not be able to remove redundancy entirely in image coding , and transform image into correlated indexes. This correlated indexes do not span distance space , so can not data compressing using distance based coding schemes. On the other hand , in point of data compression of simbols (or words) , self-organizing list coding scheme has been used. We intende to remove redundancy of indexes applying self-organizing List to vector quantizer. In this paper, self-organizing list coding of vector-quantized indexes of image, and new vector quantization sccheme which has self-organizing structure codebook are investigated. And their simulation results using monochrom images show advantage of application of self-organizing list.
