In this paper, we investigate region-based embedded wavelet compression methods and introduce region-based extensions of the Set Partitioning In Hierarchical Trees (SPIHT) and the Set Partitioning Embedded bloCK (SPECK) coding algorithms applied to the breast region of digital mammograms. We have compared these region-based extensions, called OB-SPIHT and OB-SPECK, against the original SPIHT and the new standard JPEG 2000 on five digital mam
