Abstract:The shape is one of the most significant properties used in Content Based Image Retrieval (CBIR), however for a CBIR shape representation should satisfy several properties such as rotation invariance, robustness, in this article we are trying to study and combine two shape descriptors: the shape descriptor based on the area of MPEG-7, It is defined on a unit disk in polar coordinates and the shape descriptor based outline of MPEG-7 is based on the representation of the contour scale-space curvature (CSS).
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.
