Title (EN) METHOD AND DEVICE FOR MODIFYING ATTRIBUTES OF POINTS OF A 3D SCENE
(FR) PROCÉDÉ ET DISPOSITIF DE MODIFICATION D'ATTRIBUTS DE POINTS D'UNE SCÈNE 3D
Abstract:
(EN) A method and device for modifying attributes of one or more points of a 3D scene, the attributes comprising depth attribute and texture attribute stored respectively in a depth image and a texture image. To reach that aim, at least a first point of the 3D scene is identified, the at least a first point having depth information inconsistent with regard to depth information associated with a neighborhood of the at least a first point in the depth image. It is then determined whether the attributes of the at least a first point are correctable by analyzing neighborhood of the at least a first point in the depth image and in the texture image. For each first point having correctable attributes, the attributes stored in the depth image and/or texture image are modified according to the neighborhood in the depth image and/or in the texture image.
(FR) La présente invention concerne un procédé et un dispositif pour modifier des attributs d'un ou plusieurs points d'une scène 3D, les attributs comprenant un attribut de profondeur et un attribut de texture stockés respectivement dans une image de profondeur et une image de texture. Afin d'atteindre cet objectif, au moins un premier point de la scène 3D est identifié, lesdits premiers points ayant des informations de profondeur incohérentes par rapport à des informations de profondeur associées à un voisinage desdits premiers points dans l'image de profondeur. Il est ensuite déterminé si les attributs desdits premiers points sont corrigibles par analyse du voisinage desdits premiers points dans l'image de profondeur et dans l'image de texture. Pour chaque premier point ayant des attributs corrigibles, les attributs stockés dans l'image de profondeur et/ou l'image de texture sont modifiés en fonction du voisinage dans l'image de profondeur et/ou dans l'image de texture.
