Abstract
Various exemplary embodiments relate to a method and related motion estimation unit for performing motion estimation on video data comprising a plurality of frames. The method may begin by reading a current frame of the plurality of frames from a memory of a motion estimation unit. The method may then select a motion vector for each respective block of pixels in a current row of the current frame. The step of selecting the motion vector may include, for each respective block, selecting, by the motion estimation unit, a candidate vector for at least one block directly surrounding the respective block based on a determination of whether the directly surrounding block has been processed for the current frame, calculating, for each candidate vector, a difference value, and selecting, as the motion vector, the candidate vector with the lowest difference value.
