The SPIHT algorithm is shown to implicitly use quadtree-based classification. The rate-distortion encoding performance of the classes is described, and quantization improvements presented. A new encoding algorithm combines a general SPIHT data structure with the granular gain of multi-dimensional quantization to achieve improved PSNR versus rate performance.
