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.
