N2 - The set partitioning embedded block (SPECK) algorithm is a fast and efficient technique for still image compression. In this paper, we propose a novel wavelet-based coding scheme, called prepartition SPECK (PSPECK), on the extension of SPECK. In order to improve the peak signal-to-noise ratio (PSNR) performance, we predict the significance of each set in the list of insignificant sets (LIS) by exploiting inter-subband correlation for reducing the bit budget. Furthermore, the proposed method can be combined with other quadtree-based coding techniques. Experimental results show that the proposed method outperforms SPECK, especially at high bit rates.
