Multimedia applications require certain QoS guarantees to be met in order to function properly. QoS requirements for multimedia transmission include bandwidth guarantees and temporal guarantees (delay and jitter). Existing routing protocols on MANeTs are not adequate enough to deal with these necessities imposed by multimedia traffic. In this article, an adaptation of MPLS is proposed for MANeTs. MPLS and MLDP together are employed in MANeTs to provide QoS and traffic engineering for real time multimedia traffic. These protocols are implemented and tested in the OMNeT++ network simulator. This article describes in detail the design and implementation of MPLS and MLDP.
We report on methods for using object shape and structure for matching a pair of images or an image and a drawing. These methods can be used in combination with the several methods using color and texture already in use in content based image retrieval (CBIR). Matching methods are based on edges, corners, and ribbons and the relations among them and can be controlled for rotation, translation, and scale invariance. Good results are shown on a small but diverse sample of images with man-made structure. Although we have been oriented toward CBIR because image parts are put into correspondence, the methods are also of general use in object tracking, recognition, registration, structural stereo, or perhaps even detection of shot boundaries in video.
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.
