1. A method comprising: receiving a luminance target frame and a luminance source frame of a sequence of video frames of a scene; extracting motion from the received luminance target and source frames and representing the motion as a motion vector field and weights; dividing the weights into a first set of zeros weights for motion in the motion vector field that is near zero motion and a second set of peak weights for motion in the motion field that is not near zero; comparing the zeros weights to a threshold to determine whether there is motion in the scene and if the zeros weights exceed the threshold then selecting a zero motion motion model; and adjusting a frame of the video sequence corresponding to the target frame based on the selected motion model.
