IMAGE DATA COMPRESSION USING VECTOR QUANTIZATION TECHNIQUFs

Abstract

VECTOR QUANTIZATION is a. very powerful technique for data compression. It is intrinsically superior to predictive coding, transform coding and other suboptimal procedures, since it achieves optimal rate distortion performance. In this dissertation various Vector quantization techniques have been discussed in detail. Software simulation of Pull search memory- less vector qua.ntizer has been described. A performance evaluation for this Full search memory-less vector qua.ntizer has also been presented
