Abstract: A method of processing an immersive video includes classifying view images into a basic image and an additional image, performing pruning with respect to view images by referring to a result of classification, generating atlases based on a result of pruning, generating a merged atlas by merging the atlases into one atlas, and generating configuration information of the merged atlas.

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.
