Abstract

An adaptive scheme employing pyramid structure is proposed for multiresolution encoding of still pictures. Efficiency is increased by designing a low-entropy pyramid decomposition by means of different reduction/expansion filters, and also by giving encoding priority to important features through a content-driven decision rule. Quantization error feed-back performed along the pyramid levels ensures lossless reconstruction capability and improves the robustness of the algorithm.
