An adaptive scheme employing pyramid structures is proposed for multiresolution encoding of still pictures. Efficiency is increased by designing a low-entropy pyramid decomposition and also by giving encoding priority to important features through a content-driven decision rule. Lossless reconstruction capability is ensured. Significant results are achieved.

Abstract
An adaptive scheme employing pyramid structures is proposed for multiresolution encoding of still pictures. Efficiency is increased by designing a low-entropy pyramid decomposition and also by giving encoding priority to important features through a content-driven decision rule. Lossless reconstruction capability is ensured. Significant results are achieved.File in questo prodotto:
