Abstract: Disclosed herein are an immersive video encoding method and an immersive video decoding method. The immersive video encoding method includes setting basic view images among input images corresponding to multiple views, generating an atlas image using the basic view images, performing encoding on the atlas image, and generating metadata about an encoded atlas image, wherein the atlas image includes a texture atlas or a depth atlas.

Abstract: Disclosed herein are an apparatus for estimating a camera pose using multi-view images of a 2D array structure and a method using the same. The method performed by the apparatus includes acquiring multi-view images from a 2D array camera system, forming a 2D image link structure corresponding to the multi-view images in consideration of the geometric structure of the camera system, estimating an initial camera pose based on an adjacent image extracted from the 2D image link structure and a pair of corresponding feature points, and estimating a final camera pose by reconstructing a 3D structure based on the initial camera pose and performing correction so as to minimize a reprojection error of the reconstructed 3D structure.

Abstract: Disclosed herein is a method for encoding an immersive image. The method includes detecting a non-diffuse surface in a first texture image of a first view, generating an additional texture image from the first texture image based on the detected non-diffuse surface, performing pruning on the additional texture image based on a second texture image of a second view, generating a texture atlas based on the pruned additional texture image, and encoding the texture atlas.

Abstract: Disclosed herein are an immersive video decoding method and an immersive video encoding method. The immersive video decoding method includes partitioning a current picture into multiple main blocks, determining whether each main block is to be partitioned into multiple sub-blocks, and when it is determined that each main block is to be partitioned into multiple sub-blocks, determining a partitioning type of the corresponding main block. Here, the corresponding main block may be partitioned into four or two sub-blocks depending on the partitioning type. When the corresponding main block is partitioned into multiple sub-blocks, whether depth information is to be updated for each of the sub-blocks generated by partitioning the main block may be determined.

Abstract: An image encoding method according to the present disclosure may include generating an atlas based on a plurality of viewpoint images; encoding the atlas; and encoding metadata for the atlas. In this case, the metadata may include data of a patch packed in the atlas, and the patch data may include type information of an entity corresponding to a patch.

Abstract: Disclosed herein are a method and apparatus for generating a residual image of multi-view video. The method includes generating a pruning mask of an additional view image by mapping a basic view image to the additional view image, among multi-view images, and detecting outliers in the pruning mask using color information of the basic view image and the additional view image.
