Motion compensated frame rate conversion by overlapped block-based motion estimation algorithm

Abstract

Frame Delay 7 Abstract We propose a motion compensated frame rote lipconversion (MC-FRC) algorithm adapting new hlock-hased motion estimation (BME), which is overlapped I ~ l u c k I ~ ~ ~ e d motion estimatioti (OBME). for ,frame rate ripconvcrsiuiz (FRC). Unlike conventional BME algorithms, wheri a video Jiame i.7 divided itito many non-overlapping syiiare hlocks oJ'pi.rels. the proposed BME is e.reciited rising an overlapped matching hlock in order to get more accwafe mofioii trajectoni. To redrice compritational complexif?, carised by the OBME, a srih-.sampledpi.rel hlock is usedfur tlie OBME.
