Abstract
The invention relates to a method for estimation of interframe motion fields operating on a stream of video frames, and more particularly for accelerating video output in multiframe super-resolution thus improving the efficiency of the multiframe integration. Relative motion field estimation is used between neighboring or close images instead of with respect to a reference image, for at least some of the frames within an integration window (TOI). The integration window is slid along the time axis each time by one (or two or a few) frames so that the current integration window preferably covers the majority of the frames in the previous integration window. Using relative motion estimation and then (tracking and) summing up the related motion fields enables, in each recursion, the absolute motion fields in a new integration window to be obtained without re-computing all the motion fields of earlier frames in the new integration window.
