Multiscale decomposition using median and morphological filters

JA Bangham, RV Aldridge

Research output: Contribution to conferenceOther


The small differences between the output from cascades of multiscale median and morphological filters (datasieves) is explored. It is shown that the self dual nature median filters confers statistical verity and that open/close (close/open) filters have the advantage of yielding what appears to be a 1:1 transform pair. Overall, however, they distinguish ID patterns equally well from an uncorrelated noisy background.
