摘要： 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.

摘要： 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.

摘要： An image encoding method according to the present disclosure may include classifying a plurality of view images into a basic image and an additional image; performing pruning for at least one of the plurality of view images based on a result of the classification; generating an atlas based on a result of performing the pruning; and encoding the atlas and metadata for the atlas. In this case, the metadata may include spherical harmonic function information on a point in a three-dimensional space.

摘要： A video decoding method comprises receiving a plurality of atlases and metadata, unpacking patches included in the plurality of atlases based on the plurality of atlases and the metadata, reconstructing view images including an image of a basic view and images of a plurality of additional views, by unpruning the patches based on the metadata, and synthesizing an image of a target playback view based on the view images. The metadata is data related to priorities of the view images.

摘要： A method of producing an immersive video comprises decoding an atlas, parsing a flag for the atlas, and producing a viewport image using the atlas. The flag may indicate whether the viewport image is capable of being completely produced through the atlas, and, according to a value of the flag, when the viewport image is produced, it may be determined whether an additional atlas is used in addition to the atlas.

摘要： Disclosed herein is an image encoding/decoding method and apparatus for virtual view synthesis. The image decoding for virtual view synthesis may include decoding texture information and depth information of at least one or more basic view images and at least one or more additional view images from a bit stream and synthesizing a virtual view on the basis of the texture information and the depth information, wherein the basic view image and the additional view image comprise a non-empty region and an empty region, and wherein the synthesizing of the virtual view comprises determining the non-empty region through a specific value in the depth information and a threshold and synthesizing the virtual view by using the determined non-empty region.

摘要： 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.

摘要： Disclosed herein is an immersive video processing method. The immersive video processing method includes: determining a priority order of pruning for input videos; extracting patches from the input videos based on the priority order of pruning; generating at least one atlas based on the extracted patches; and encoding metadata. Herein, the metadata may include information on a priority order of pruning among input videos.
