摘要:The set partitioning in hierarchical trees (SPIHT) consist of linked lists to track coefficients, thusrequiring large memory. In this paper, we propose a resilient and energy-efficient SPIHT image compression schemewith lifting scheme to calculate the discrete wavelet transformed coefficients of image. A state table is used instead oflists which uses 0.25 bit per coefficient marker to keep track of set partitions, thus replacing dynamic memory. Thereduction in memory requirement facilitates image transmission over energy constrained wireless sensor network.Simulation results show that the listless SPIHT coder saves 96.35% energy which is resilient also.
