LOSSLESS IMAGE COMPRESSION VIA LIFTING SCHEME AND SPIHT
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 4
Abstract
Image compression is useful because it helps to reduce the consumption of expensive resources, such as hard disk space or transmission bandwidth .Many compression techniques are in place but there is a scope for high compression with good reconstruction of original image. The problem of reconstruction of data from sub signals from each filter channel is removed by lifting scheme because this structure itself assures reversibility. In this paper we are introducing lifting scheme with SPIHT coder for image compression and the results are obtained for compression ratio, PSNR and RMSE. A study in lossless image compression using the lifting scheme is presented. We first suggest why lossless image compression is an important issue and the general idea behind lifting.
