A progressive image-coding algorithm that uses a combination of the setpartitioning in hierarchicaltree (SPIHT) algorithm and an embedded trellis-coded quantiser (E-TCQ) is proposed. Using the hierarchical quadtree structure, 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 storage memory.
