Abstract: A method of processing an immersive video includes classifying each of a plurality of objects included in a view image as one of a first object group and a second object group, acquiring a patch for each of the plurality of objects, and packing patches to generate at least one atlas. In this instance, patches derived from objects belonging to the first object group may be packed in a different region or a different atlas from a region or an atlas of patches derived from objects belonging to the second object group.

Abstract: A method of encoding an immersive image according to the present disclosure comprises classifying a plurality of view images into a basic image and an additional image, generating a plurality of texture atlases based on the plurality of view images, generating a first depth atlas including depth information of view images included in a first texture atlas among the plurality of texture atlases, and generating a second depth atlas including depth information of view images included in remaining texture atlases other than the first texture atlas.

Abstract: A video encoding/decoding method and apparatus is provided. The image decoding method includes acquiring image data of images of a plurality of views, determining a basic view and a plurality of reference views among the plurality of views, determining a pruning order of the plurality of reference views, and parsing the image data based on the pruning order and decoding an image of the basic view and images of the plurality of reference views.

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.

Abstract: Disclosed herein is a method for rectifying a 2D multi-view image. The method for rectifying a 2D multi-view image according to an embodiment of the present disclosure may include: detecting uniformly the at least one feature point in each region unit distinguished by considering a distribution of feature points of a plurality of input images: removing an error of the least one feature point; determining a corresponding pair for a vertical or horizontal direction of the at least one feature point; by considering an arrangement relationship of the plurality of input images, projecting the at least one feature point onto a projection plane; determining a disparity error for a corresponding pair for the at least one feature point that is projected onto the projection plane; and, by considering the disparity error, performing image rectification based on the at least one feature point.

Abstract: Disclosed herein is an immersive video processing method. The immersive video processing method may include classifying a multiplicity of source view videos into base view videos and additional view videos, generating residual data for the additional view videos, packing a patch, which is generated based on the residual data, into an altas video, and generating metadata for the patch.

Abstract: A video encoding method includes classifying a plurality of view images into a basic image and additional images, performing pruning on at least one of the plurality of view images on the basis of the classification result, generating an atlas on the basis of the pruning result, and encoding the atlas and metadata for the atlas. Here, the metadata includes a first flag indicating whether depth estimation needs to be performed on a decoder side.
