Abstract
A method comprises, for a plurality of interpolated pixels in an interpolated video frame, classifying an interpolated pixel of the plurality as one of stationary, moving, covered, and uncovered, and then setting components of the interpolated pixel to components of a previous pixel from a previous video frame, the previous pixel corresponding to the interpolated pixel in the video frame. If the interpolated pixel is uncovered, components of the interpolated pixel are set to components of a current pixel from a current video frame if the interpolated pixel is uncovered, the current pixel corresponding to the interpolated pixel in the video frame. If the interpolated pixel is moving, the interpolated pixel is set to a function of the current pixel and the previous pixel.
