Abstract: A method of processing media data. The method includes determining, for a conversion between the media data and a media data file, that a preselection element includes an indicator, wherein the indicator indicates that a purpose of the preselection element is for providing a picture-in-picture experience where a supplementary video appears to be overlaid on a target picture-in-picture region in a main video; and performing a conversion between the media data and the media data file based on the indicator. A corresponding video coding apparatus and non-transitory computer-readable recording medium are also disclosed.

Abstract: Methods, systems, apparatus for media processing are described. One example method of digital media processing includes determining, for a conversion between visual media data and a bitstream of the visual media data, how to apply one or more convolutional neural network filters to at least some samples of a video unit of the visual media data according to a rule; and performing the conversion based on the determining.

Abstract: Methods and apparatus for processing visual media data are described. One example method of processing visual media data includes performing a conversion between visual media data and a bitstream of the visual media data including multiple layers according to a format rule; wherein the format rule specifies that a supplemental enhancement information (SEI) message is included in the bitstream to indicate that it is allowed for a decoder to decode 1) a dependent random access point (DRAP) picture in a layer associated with the SEI message and/or 2) pictures included in the layer and following the DRAP picture in a decoding order and an output order, without having to decode other pictures in the layer except for an intra random access point (IRAP) picture associated with the DRAP picture.

Abstract: Methods and apparatus for processing visual media data are described. One example method of processing visual media data includes performing a conversion between visual media data and a bitstream of the visual media data according to a format rule, wherein the format rule specifies whether and how a second type of supplemental enhancement information (SEI) message that is different from a first type of SEI message is included in the bitstream, and wherein the first type of the SEI message and the second type of the SEI message indicate a first type of dependent random access point (DRAP) picture and a second type of DRAP picture, respectively.

Abstract: Systems, methods and apparatus for processing visual media data are described. One example method includes performing (1202) a conversion between visual media data and a visual media file that includes one or more tracks that store one or more bitstreams of the visual media data according to a format rule; wherein the visual media file includes a base track that references one or more subpicture tracks that store coded information for one or more subpictures of the visual media data, and wherein the format rule specifies a process used to reconstruct a video unit from a sample in the base track and the one or more subpicture tracks.

Abstract: Systems, methods and apparatus for processing visual media data are described. One example method includes performing a conversion between visual media data and a visual media file that includes one or more tracks that store one or more bitstreams of the visual media data according to a format rule; wherein the visual media file includes an operating point record and an operating point group box, and wherein the format rule specifies to include, for each operating point indicated in the visual media file, in the operating point record and the operating point group box, a first element indicative of a chroma format, a second element indictive of a bit depth information, a third element indicative of a maximum picture width, and/or a fourth element indicative of a maximum picture height.

Abstract: Systems, methods and apparatus for processing image data are described. One example method includes performing a conversion between a visual media file and a bitstream. The visual media file comprises a sequence of one or more pictures according to a media file format, and the bitstream comprises one or more access units according to a video coding format. The bitstream is coded according to the video coding format. The media file format specifies that an image item of a specific type value in the visual media file includes a single access unit of the bitstream. The single access unit is either an Intra Random Access Picture (IRAP) access unit or a Gradual Decoding Refresh (GDR) access unit according to the video coding format. All pictures in the GDR access unit are identified as a recovery point in the bitstream.

Abstract: Embodiments of the disclosure relate to interactive point-based image editing. According to example embodiments of the present disclosure, a user edit input for a source image is obtained to indicate at least one handle point and at least one target point in the source image. A feature map is extracted from the source image using a diffusion model at an iteration step of an inverse denoising diffusion process performed on the source image. The feature map is then updated based on the user edit input. Then a target image is generated based on the updated feature map using the diffusion model through a denoising diffusion process performed on the updated feature map.
