The scenario we address in this paper is high quality interpolation of 'talking head' lecture video. It is often desired to enlarge streaming media of this type with frame size NtimesM to a higher spatial dimension of, let's say, 2Ntimes2M. Simple interpolation methods are sometimes preferred because of complexity constraints in processing. But even in the absence of such constraints, the quality of the image degrades as the image size is increased, typically resulting in a blurred version of… CONTINUE READING
