A Novel Method of Image Compression Based on Wavelet Speck and Vector Quantization

Abstract

Lossless image compression is critical task in image processing. Vector quantization method is fast compression method of image compression, but this is lossy technique of image compression. But gives the better compression ratio and PSNR value. the better compression rate can be achieved by vector quantization (VQ) and SVQ scheme, but the quality of the recovered image is about 16 to 47 dB in PSNR, and the methods about quality improvement is limited, so how to improve the image's quality with the help of fcm and svq method
