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: 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.

Abstract: Disclosed herein is a method for piecewise linear scaling of a geometry atlas, the method including generating min-max normalized depth values and generating geometry atlases by scaling the depth values so as to correspond to the gradients of multiple linear intervals.
