Abstract Linde–Buzo–Gray (LBG), a traditional method of vector quantization (VQ) generates a local optimal codebook which results in lower PSNR value. The performance of vector quantization (VQ)… (More)
Vector quantization (VQ) is the technique of image compression that aims to find the closest codebook by training test images. Linde Buzo and Gray (LBG) algorithm is the simplest technique of VQ but… (More)
Linde-Buzo-Gray LBG Vector Quantization VQ, technically generates local codebook after many runs on different sets of training images for image compression. The key role of VQ is to generate global… (More)
ABSTRACTImage compression is very significant process in image transmission at high data rate over a communication channel and to increase the storage capacity of storage device. Ordinary image… (More)
