Digital image coding using vector quantization (VQ) based techniques provides low-bit rates and high quality coded images, at the expense of intensive computational demands. The computational requirement due to the encoding search process, had hinder

It is a well-known fact that since the emergence of Internet, Web and e-commerce applications have become increasingly popular. With the growing demand of Web-based applications, a number of issues have also increased proportionately regarding scalab

A real-time vector quantizer (VQ) architecture for broadcast quality encoding of color TV images is presented. The architecture maps the mean/quantized residual vector quantizer (MQRVQ), an extension of mean/residual VQ, onto a VLSI/LSI chip set. The

Although the generalized Lloyd algorithm (GLA) minimizes the average squared error on the training set, the squared-error distortion measure cannot discriminate between edge and shade vectors. Moreover, the GLA is dependent on the initial codebook. T

This paper discusses the results of a survey on various lossless and lossy image compression algorithms for on-board processing in spacecrafts. Three performance metrics are used to evaluate image compression algorithms and choose the most suitable o

Four objective measures and a subjective measure are used to evaluate the images reconstructed by a mean/quantized residual vector quantizer (MQRVQ) algorithm. These reconstructed images are also evaluated using a subjective evaluation method recomme

A VLSI architecture for real-time high-quality coding of color TV images at a fixed bit rate of 1.12 BPP is developed. The architecture exploits pipeline/parallel processing an don-chip memory to partition a large codebook into smaller on-chip subcod
