The success of a new display technology such as plasma is strongly related to the final picture quality assessed by the customer's eyes. The human visual system (HVS) characteristics enable the definition of new cost-efficient methods to significantly reduce the visibility of all plasma-specific artifacts. Simple optimized encoding methods based on the luminance perception will be presented as well as more-complicated algorithms based on motion perception.
Abstract— Today, methods for power management of plasma display panels (PDP) have been developed in order to provide a maximum peak white for a given picture content with stable power consumption. However, the quality of the gray‐scale portrayal with such concepts is far from the actual CRT standards. We have developed a new PDP encoding concept called Metacode to improve gray‐scale quality during all power and contrast adjustment towards CRT level.
False contours occurs on PDP since the eye tracks moving objects in a video scene. To correctly render these moving objects the definitive solution is to use the motion information and pre‐compensate the eye's tracking. Such a solution will be presented using a pixel‐based motion estimator combined to an efficient video coding technique.
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.
