Abstract: Disclosed herein are a method, an apparatus and a storage medium for image encoding/decoding. For efficient image compression, efficient syntax is required. Pieces of information required for image decoding may be structurally or semantically associated with each other. Based on this association, whether signaling of one piece of information is to be performed may be determined based on another piece of information. Further, based on this association, the signaling order or priority of multiple pieces of information may be determined. Depending on this determination, based on the number of subpictures present in a picture in high-level syntax, the number of slices present in the picture may be selectively signaled.

Abstract: The present invention relates to an image encoding/decoding method and apparatus. The image decoding method according to the present invention may comprise acquiring transform coefficients distribution information of a neighboring block from a bitstream; direction-adaptively determining an intra prediction mode of a current block to be decoded, according to the transform coefficients distribution information of the neighboring block; and reconstructing the current block, based on the determined intra prediction mode, wherein the direction-adaptively determining includes determining similarity flag information corresponding to the neighboring block, based on the transform coefficients distribution information of the neighboring block.

Abstract: 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.
