摘要
A quad-tree embedded image coding technique is used in combination with a bit-plane encoding technique to provide an efficient and low complexity embedded image coding system. A simple quad-tree method identifies coefficients as significant, insignificant, or refinement at each successive quantization level. The quad-tree technique is used instead of the zero-tree or hierarchical tree used in previous encoders.
