Various filtering methods of motion vector fields
Ján Gamec · 2008
The Block matching algorithms suffers from limitation concerning the fidelity of the predicted image: blocking effect is introduced for the lack of coherence of the estimated motion to the actual motion. It is possible to partially overcome this drawback by smoothing the estimated vector field in a further stage. Smoothing can be accomplished, for example, by using various filtering methods. In this paper, it is main purpose to present the motion estimation and filtering techniques that give consideration to both estimation performance and computational efficiency.
