In this paper we describe how JPEG 2000 can be used to define, search for, display, and link specific regions of interests which are subsets of the much larger image (and hence a file subset of a much smaller data file). The advantage of this approach is that these segments can be individually searched; displayed at predetermined access and resolution limits; and linked to supporting or extended data sources.
