The present disclosure relates to an image processing apparatus and method that enable linking between a 3D spatial region and an atlas tile group.

Link information is generated and signaled, in which the link information is stored in a file together with a bitstream of a point cloud expressing an object having a three-dimensional shape as a set of points, and the link information links a 3D spatial region of the point cloud with an atlas tile group. On the basis of the link information, the 3D spatial region and the atlas tile group that correspond to a desired three-dimensional space are selected. The present disclosure can be applied to, for example, an image processing apparatus, an information processing apparatus, an image processing method, an information processing method, or the like.

An apparatus (200) for receiving an input video data stream according to an embodiment is provided. The input video data stream has a video encoded thereinto. The apparatus (200) is configured to generate an output video data stream from the input video data stream.

An image decoding method according to the present disclosure presents indication information related to whether deblocking parameters for a deblocking filtering procedure exist in a picture header or a slice header.

A (decoded) picture may be split into subpictures/tiles. Information on the subpictures may be obtained by a decoding device, and a decoding procedure may be performed on the basis of the information on the subpictures. In addition, information on the tiles may be obtained by a decoding device, and a decoding procedure may be performed on the basis of the information on the tiles. According to embodiments of the present document, subpicture-related information and tile-related information can be efficiently signaled, and an in-loop filtering procedure can be performed on the basis of the subpicture-related information.

An image encoding/decoding method and apparatus for performing encoding/decoding using BDPCM and a storage medium storing a bitstream are provided. An image decoding method performed by an image decoding apparatus may comprise obtaining first information indicating whether block-based differential pulse coded modulation (BDPCM) is applicable to a current image, obtaining second information indicating whether to apply the BDPCM to a current block in the current image based on the first information, obtaining third information indicating a prediction direction of the BDPCM based on the second information, and applying the BDPCM to the current block based on the prediction direction of the BDPCM. The first information may indicate whether BDPCM is enabled for both a luma component and a chroma component of the current block.
