摘要：
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 vs, rate performance.
