ABSTRACT
This work gives an effective and efficient approach for image compression which is based on lifting wavelets. Here the image is decomposed into n-level binary sequence; this binary form image is then processed using lifting wavelet transform. The alternate modification of decomposed sequence enables to eliminate the delay of one sample which is more prominently available in compression done with conventional discrete wavelet transform. In this work the compression of image is achieved using lifting wavelets to have 11.05% improvement in PSNR and 35.89% improvement in compression ratio.
