MPEG-4 met l'accent sur l'efficacité du codage et permet l'accès et la transmission basés sur le contenu d'objets de forme arbitraire. Il aborde le codage d'objets vidéo à l'aide du codage de forme, de l'estimation de mouvement et du codage de texture pour l'interactivité, un taux de compression élevé et une évolutivité. Dans cette lettre, une méthode avancée de codage de forme basée sur les sommets et adaptative aux objets est proposée pour coder la forme des objets vidéo. Cette méthode exploite la représentation basée sur les octants pour représenter la relation entre les sommets adjacents et cette relation peut être utilisée pour améliorer l'efficacité du codage. Les résultats de simulation démontrent que la méthode proposée peut réduire davantage de bits pour les sommets rapprochés.

Abstract: MPEG-4 emphasizes on coding efficiency and allows for content-based access and transmission of arbitrary shaped object. It addresses the encoding of video object using shape coding, motion estimation, and texture coding for interactivity, high compression ratio, and scalability. In this letter, an advanced object-adaptive vertex-based shape coding method is proposed for encoding the shape of video objects. This method exploits octant-based representation to represent the relation of adjacent vertices and that relation can be used to improve coding efficiency. Simulation results demonstrate that the proposed method may reduce more bits for closely spaced vertices.
