Anti-extensive connected operators with application to image sequences

Abstract

Connected operators are increasingly used in image processing They are at tractive in applications where the signal has to be simplified without loosing information about the contours A large number of simplification criteria such as size area con trast or complexity can be obtained with these operators In this paper we deal with a motion oriented connected operator This operator eliminates from the original sequence the components that do not undergo a specic motion ( defined as filtering parameter) while the remaining ob jects are almost perfectly preserved
