Optimal quadtree for variable block size motion estimation

  title={Optimal quadtree for variable block size motion estimation},
  author={Jungwoo Lee},
In this paper, we present a new approach to find the best quadtree for variable block size (VBS) motion estimation. In this approach, the quantizer which encodes the prediction residual is also jointly optimized in a rate-distortion sense. The desired balance of the bit allocation between the motion vector coding and the residual error coding is achieved by a Lagrange multiplier approach for the joint optimization problem. A fast tree optimization technique is used to reduce the computational… CONTINUE READING
