Vector quantizationIn many multimedia applications, such as image storage and transmission image, compression plays a major role. The fundamental objective of image compression is to represent an image with least number of bits of an acceptable image quality. A technique based on second-generation ...

A novel approach to image compression using vector quantization of linear (one-step) prediction errors is presented in this paper. In order to minimize the image reconstruction error, we choose the optimum predictor coefficients (in a least-squares sense) that satisfy the additional constraint that...

Image-compression algorithms based on vector quantization (VQ) techniques have been researched for years. Recently, such algorithms have been implemented in hardware by several graphics chip vendors. Unlike DXTn, VQ decompression is as easy to do in software as it is in hardware, and might be ju...
This paper addresses a new image compression algorithm that employs the quadtree decomposition and the projection vector quantization (PVQ). We examine the relationship between the image object and its projection data and discuss the image reconstruction problem from limited data. By adopting the quadtr...
