Techniques for motion estimation are disclosed. For example, embodiments may determine error metric lower bound values for a block in a current image, where each of the error metric lower bound values corresponds to a search position in a reference image. Based on a separation threshold, a plurality of candidate positions may be identified from the search positions. A matching position is then identified from the candidate positions. Based on the matching position, a motion vector is determined. |
