| 摘 要： | This letter exploits fundamental characteristics of a wavelet transform image to form a progressive octave-based spatial resolution. Each wavelet subband is coded based on zeroblock and quardtree partitioning ordering scheme with memory optimization technique. Tile method proposed in this letter is of low complexity and efficient for Internet plug-in software.
