발명의 명칭: (EN) METHOD FOR PROCESSING PROJECTION-BASED FRAME THAT INCLUDES AT LEAST ONE PROJECTION FACE PACKED IN 360-DEGREE VIRTUAL REALITY PROJECTION LAYOUT
(FR) PROCÉDÉ DE TRAITEMENT DE TRAME À BASE DE PROJECTION QUI COMPREND AU MOINS UNE FACE DE PROJECTION CONDITIONNÉE DANS UNE DISPOSITION DE PROJECTION DE RÉALITÉ VIRTUELLE À 360 DEGRÉS
요약서:
(EN) A video processing method includes: obtaining a plurality of projection faces from an omnidirectional content of a sphere, wherein the omnidirectional content of the sphere is mapped onto the projection faces via cubemap projection, and the projection faces comprise a first projection face; obtaining, by a re-sampling circuit, a first re-sampled projection face by re-sampling at least a portion of the first projection face through non-uniform mapping; generating a projection-based frame according to a projection layout of the cubemap projection, wherein the projection-based frame comprises the first re-sampled projection face packed in the projection layout; and encoding the projection-based frame to generate a part of a bitstream.
(FR) L'invention concerne un procédé de traitement vidéo comprenant les étapes suivantes : obtention d'une pluralité de faces de projection à partir d'un contenu omnidirectionnel d'une sphère, le contenu omnidirectionnel de la sphère étant mis en correspondance avec les faces de projection par le biais d'une projection de carte de cube, et les faces de projection comprenant une première face de projection ; obtention, par un circuit de ré-échantillonnage, d'une première face de projection ré-échantillonnée par ré-échantillonnage d'au moins une portion de la première face de projection par le biais d'une mise en correspondance non uniforme ; génération d'une trame à base de projection conformément à une disposition de projection de la projection de carte de cube, la trame à base de projection comprenant la première face de projection ré-échantillonnée conditionnée dans la disposition de projection ; et codage de la trame à base de projection pour générer une partie d'un train de bits.
