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: 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 an apparatus and method for removing redundant data between multi-view videos. 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 revalidating the pruning mask using color information of the basic view image and the additional view image. Revalidating the pruning mask may include defining a color relationship between the basic view image and the additional view image by extracting predetermined sample values from corresponding pixels between the basic view image and the additional view image, which are included in the pruning candidate group of the pruning mask, and detecting pixels that do not match the defined color relationship, among the pixels in the pruning mask, as outliers.

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.
