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.

Abstract: Disclosed herein is an immersive video processing method. The immersive video processing method includes: determining a priority order of pruning for source videos; extracting patches from the source 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 first threshold information that becomes a criterion for distinguishing between a valid pixel and an invalid pixel in the atlas video.

Abstract: A method for decoding a video including a plurality of views, according to one embodiment of the present invention, comprises the steps of: configuring a base merge motion candidate list by using motion information of neighboring blocks and a time correspondence block of a current block; configuring an extended merge motion information list by using motion information of a depth information map and a video view different from the current block; and determining whether neighboring block motion information contained in the base merge motion candidate list is derived through view synthesis prediction.
