A new fast motion estimation algorithm based on the loop–epipolar constraint for multiview video coding

There lie geometric constraints between neighboring frames in multiview video sequences. The geometric constraints are valuable for reducing spatial and temporal redundancy in multiview video coding (MVC).

Popis
Shrnutí:There lie geometric constraints between neighboring frames in multiview video sequences. The geometric constraints are valuable for reducing spatial and temporal redundancy in multiview video coding (MVC). In this paper, we propose a new fast motion estimation algorithm based on the loop–epipolar constraint which combines loop and epipolar constraints. A practical search technique is designed according to the characteristics of the loop–epipolar constraint. Experimental results show that the proposed algorithm is efficient for sequences under different multiview camera setups. ► A fast motion estimation algorithm is proposed based on the loop–epipolar constraint. ► The loop–epipolar constraint combines loop and epipolar constraints. ► A practical search technique is designed according to the characteristics of the loop–epipolar constraint. ► The proposed algorithm is efficient for different sequences.
