The paper describes the architecture of an image coprocessor based on a linear array of elementary processors. The system has been designed for real-time vision applications and embeds a direct 1 / 0 interface to a camera device.The instruction set of the elementary processors is based on morphological match operators on a reduced 5 x 5 neighborhood.Two additional communication mechanisms, one fixed and one programmable, provide both global and multiple communication channels among processing elements which are not directly connected.
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.
