An optical flow-based motion estimation algorithm is proposed for video coding. The algorithm is based on the fact that true motion vectors have similar characteristics to optical flow vectors. The algorithm uses block matching motion estimation with an adaptive search region. The search region is computed from motion fields that are estimated based on the optical flow. The results obtained using test images show that the proposed algorithm can produce a significant improvement compared with previous optical flow algorithm and block matching algorithm.

AB - An optical flow-based motion estimation algorithm is proposed for video coding. The algorithm is based on the fact that true motion vectors have similar characteristics to optical flow vectors. The algorithm uses block matching motion estimation with an adaptive search region. The search region is computed from motion fields that are estimated based on the optical flow. The results obtained using test images show that the proposed algorithm can produce a significant improvement compared with previous optical flow algorithm and block matching algorithm.
