1. A machine-implemented method, comprising:

  • computing a motion estimation search window for a first block of a first frame of a video based on a mean of motion vectors associated with other blocks of the video;

    selecting a second block of a second frame of the video within the motion estimation search window and a third block within a third frame of the video based on a motion vector from the first block to the second block and a measure of visual similarity between the second and third blocks; and

    deriving a motion vector for the first block based on one or more of the motion vector from the first block to the second block and a motion vector from the first block to the third block.
