My. Hu et Tb. Tang, Progressive image coding using set partitioning in hierarchical tree algorithm and embedded trellis-coded quantiser, ELECTR LETT, 37(9), 2001, pp. 561-563
A progressive image-coding algorithm that uses a combination of the set par
titioning in hierarchical tree (SPIHT) algorithm and an embedded trellis-co
ded quantiser (E-TCQ) is proposed. Using the hierarchical quadtree structur
e, a significant map of coefficients is encoded. The E-TCQ is then used to
refine the amplitude of the method. It is shown that this method gives good
performance, with very little increase in computational complexity and sto
rage memory.
