Abstract

A novel lossy image-compression scheme is proposed in this paper. A two-step structure is embedded in this codec. A spline-based directional lifting wavelet transform is used to decorrelate the image data in the first step. Then in the second step, an improved Set Partitioning in Hierarchical Trees (SPIHT) algorithm based on binary tree is developed to code the wavelet coefficients. The numerical results demonstrated the efficiency of the proposed approach to achieve significant gains in terms of PSNR, BD-PSNR and SSIM for all test images. It offers better results compared to the existing ones.
