Abstract
A method (and system) for video coding includes receiving a first reference frame having a first pixel value at a first pixel position, a second reference frame having a second pixel value at a second pixel position, and a third reference frame having a third pixel value at a third pixel position, determining a first motion vector between the first pixel position and the second pixel position, determining a second motion vector between the second pixel position and the third pixel position, and determining a fourth pixel value for a fourth frame based upon a linear or nonlinear combination of the first pixel value, the second pixel value, and the third pixel value.
