Dans cet article, nous proposons un nouvel algorithme de lissage des vecteurs de mouvement utilisant un filtrage médian vectoriel pondéré basé sur la direction des bords pour l'interpolation de trame. Le système WVM (Weighted Vector Median) proposé ajuste les valeurs de pondération en fonction de la direction du bord, qui est dérivée de la cohérence spatiale entre la continuité de la direction du bord d'un objet en mouvement et la fiabilité du vecteur de mouvement (MV). Le schéma de pondération basé sur les bords supprime l'effet des valeurs aberrantes et irrégulières du processus de lissage MV. Les résultats de la simulation montrent que l'algorithme proposé peut corriger les mauvais vecteurs de mouvement et ainsi améliorer la qualité visuelle subjective et objective par rapport aux méthodes conventionnelles.

Abstract: In this paper, we propose a new motion vector smoothing algorithm using weighted vector median filtering based on edge direction for frame interpolation. The proposed WVM (Weighted Vector Median) system adjusts the weighting values based on edge direction, which is derived from spatial coherence between the edge direction continuity of a moving object and motion vector (MV) reliability. The edge based weighting scheme removes the effect of outliers and irregular MVs from the MV smoothing process. Simulation results show that the proposed algorithm can correct wrong motion vectors and thus improve both the subjective and objective visual quality compared with conventional methods.
