%X This paper exploits the distribution of energy and correlation between various components of sub-bands and modifyies the SPIHT algorithm.In this scheme,insignificant coefficients of first component in high-frequency sub-bands that correspond to the same spatial location in other components can be used to reduce the scanning scope in the process of invalid set discrimination.Both theoretic analysis and experiment results confirm good compression performance and low complexity at the same time.
