Abstract

Based on the SPIHT algorithms, we define two modifications to develop a simpler image coding method. The first concept is obtained from the relationship between the bit-planes and the target bit-rate. The second concept is obtained from the relationship between the initial threshold and the target bit-rate. Based on the abovementioned concepts, we can discard the refinement pass and improve the image quality at different target bit-rates. The simulation results show that in comparison with the original SPIHT algorithm, the proposed algorithm can reduce memory usage by approximately 50% and computation time by approximately 30% with an acceptable PSNR loss.
