Abstract: An immersive video processing method according to the present invention includes: classifying view videos into a base video and an additional video; performing pruning for the view videos by referring to a result of the classification; generating an atlas based on a result of the pruning; determining a depth parameter of each view in the atlas; and encoding information indicating whether or not updating of the depth parameter is needed, based on whether or not the depth parameter of each view in the atlas is identical as in a previous atlas.

Abstract: An image encoding method according to the present disclosure may include classifying viewpoint images into a basic image and an additional image; performing pruning on an additional image based on the classification result, generating an atlas by packing patches obtained as a result of performing the pruning; and encoding the atlas and metadata for the atlas. In this case, a margin may be set for a patch within the atlas.
