    Abstract: A method by which a video decoding device decodes a video, according to the present document, can comprise the steps of: parsing, from a bitstream, number information related to the number of slices of which the height within a tile of a current picture is explicitly signaled; parsing, from the bitstream, on the basis of the number information, height information related to the height of the slices of which the height is explicitly signaled; deriving the number of slices in the tile on the basis of the number information and the height information; generating prediction samples by predicting the current block of the current picture on the basis of the slices within the tile; generating reconstructed samples on the basis of the prediction samples; and generating a reconstructed picture for the current picture on the basis of the reconstructed samples.

    Abstract: De acuerdo con las modalidades descritas en este documento, se pueden usar subimágenes y/o límites virtuales para codificar una imagen. Por ejemplo, las subimágenes en la imagen actual se pueden usar para predecir, reconstruir y/o filtrar la imagen actual. Los límites virtuales se pueden usar para filtrar muestras reconstruidas de la imagen actual. A través de la codificación de imágenes con base en las subimágenes y/o los límites virtuales de acuerdo con las modalidades descritas en este documento, se puede mejorar la calidad subjetiva/objetiva de una imagen y se puede reducir el consumo de recursos de hardware necesarios para la codificación.

    Abstract: According to embodiments described herein, sub-pictures and/or virtual boundaries can be used for coding an image. For example, sub-pictures in the current picture can be used for predicting, reconstructing, and/or filtering the current picture. Virtual boundaries can be used for filtering reconstructed samples of the current picture. Through image coding based on the sub-pictures and/or virtual boundaries according to embodiments described herein, the subjective/objective quality of an image can be improved, and the consumption of hardware resources necessary for the coding can be reduced.

    Abstract: A video decoding method performed by a video decoding apparatus, according to the present document, comprises the steps of: parsing number information about the number of slices of which heights are explicitly signaled in a tile of a current picture from a bitstream; parsing height information about the heights of slices of which heights are explicitly signaled from the bitstream on the basis of the number information; deriving the number of slices in the tile on the basis of the number information and the height information; and decoding the current picture on the basis of the slices in the tile, wherein the height information includes the same number of syntax elements as a value of the number information, and on the basis of the value of the number information being n, the heights of a 0th slice to an n-1th slice in the tile may be derived on the basis of the syntax elements.

    Abstract: In relation to an in-loop filtering procedure described in the present document, a virtual boundary is defined so as to further increase the subjective/objective visual quality of a restored picture and the in-loop filtering procedure can be applied across the virtual boundary. The virtual boundary can include, for example, a discontinuous edge such as a 360-degree image, a VR image, or picture in picture (PIP). For example, the virtual boundary can be at a predetermined appointed position, and the existence and/or the position thereof can be signaled. Embodiments of the present document present a method for efficiently signaling virtual boundary-related information.

    Abstract: According to embodiments described herein, sub-pictures and/or virtual boundaries can be used for coding an image. For example, sub-pictures in the current picture can be used for predicting, reconstructing, and/or filtering the current picture. Virtual boundaries can be used for filtering reconstructed samples of the current picture. Through image coding based on the sub-pictures and/or virtual boundaries according to embodiments described herein, the subjective/objective quality of an image can be improved, and the consumption of hardware resources necessary for the coding can be reduced.
