Paper Abstract

Field rate upconversion is used in many modem television systems in order to improve the picture quality. Motion estimation by motion vector computation is used to improve motion portrayal. Usually, motion compensated upconversion requires some further processing of the standard 50 Hz motion vectors. In this paper, a nonlinear algorithm, called vector median, is introduced for this purpose. The suggested postprocessing was applied to the High Definition Multiplexed Analogue Components (HD-MAC) system introduced by the Eureka 95 project.
