A hierarchical pruned tree-structured vector quantizer (PTSVQ) employing multi-stage PTSVQ's is introduced to encode image wavelet coefficients. The result is a low-complexity and scalable image coding system. The effects of non-square selection of the block sizes and normalization on the performance of the system are investigated.
