Abstract:We aim to study the set of color sets of continuous regions of an image given
as a matrix of $m$ rows over $n\geq m$ columns where each element in the matrix
is an integer from $[1,\sigma]$ named a {\em color}.
The set of distinct colors in a region is called fingerprint. We aim to
compute, index and query the fingerprints of all rectangular regions named
rectangles. The set of all such fingerprints is denoted by ${\cal F}$. A
rectangle is {\em maximal} if it is not contained in a greater rectangle with
the … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
