Cet article propose un schéma de codage adaptatif efficace par carte de profondeur pour générer des images de vue virtuelle en vidéo 3D. Des images à vue virtuelle peuvent être générées par interpolation de vue sur la base de la carte de profondeur décodée de l'image. Le schéma de codage de carte de profondeur proposé est conçu pour avoir une nouvelle méthode de codage à plan binaire basée sur le codage gris pour coder efficacement les images de carte de profondeur sur les zones limites de l'objet, ainsi que le schéma de codage conventionnel basé sur la DCT (H .264/AVC) pour coder efficacement les images de la zone intérieure des objets ou les images de la carte de profondeur d'arrière-plan. Les résultats de simulation montrent que le schéma de codage proposé, par rapport au schéma de codage H.264/AVC, améliore les économies de taux BD de 6.77 % à 10.28 % et que le BD-PSNR gagne de 0.42 dB à 0.68 dB. Il améliore également la qualité d'image subjective des images de vue virtuelle synthétisées à l'aide de cartes de profondeur décodées.

Abstract: This paper proposes an efficient adaptive depth-map coding scheme for generating virtual-view images in 3D-video. Virtual-view images can be generated by view-interpolation based on the decoded depth-map of the image. The proposed depth-map coding scheme is designed to have a new gray-coding-based bit-plane coding method for efficiently coding the depth-map images on the object-boundary areas, as well as the conventional DCT-based coding scheme (H.264/AVC) for efficiently coding the inside area images of the objects or the background depth-map images. Simulation results show that the proposed coding scheme, in comparison with the H.264/AVC coding scheme, improves the BD-rate savings 6.77%-10.28% and the BD-PSNR gains 0.42 dB-0.68 dB. It also improves the subjective picture quality of synthesized virtual-view images using decoded depth-maps.
