Abstract
Binary pyramids in two and three dimensions can be used for multiresolution representation. The "standard" OR and AND pyramids have serious drawbacks, as they distort the shape significantly; therefore they can seldom be used effectively. Here we present alternative approaches to build binary pyrami ds, aimed at improving shape preservation (and, as far as possible, topolog y preservation) in lower resolutions. The algorithms are easy to implement and produce good results. (C) 1999 Academic Press.
