Abstract: Embodiments of the present disclosure provide a solution for image/video super resolution. A method for image processing is proposed. The method comprises: receiving a first image with a first resolution and at least one reference image associated with the first image, the first image and the at least one reference image being associated with a same video; determining a difference between the first image and the at least one reference image; and generating a second image with a second resolution based on the difference, the first image and the at least one reference image, the second resolution being higher than the first resolution.

Abstract: A method implemented by a video coding apparatus includes applying a neural network (NN) filter to an unfiltered sample of a video unit to generate a filtered sample. The NN filter is applied based on a syntax element of the video unit. The method also includes converting between a video media file and a bitstream based on the filtered sample that was generated.

Abstract: A mechanism for processing video data implemented by a video coding apparatus is disclosed. The mechanism determines usage of one or more of a separate tree coding and a partitioning beyond a minimum size threshold for a video unit. The mechanism also disables a cross-component coding tool for the video unit based on the determination. A conversion between a visual media data and a bitstream is performed in accordance with the coding tool being disabled.

Abstract: A video processing method includes performing a conversion between a video comprising multiple video units and a coded representation of the video in which the multiple video units are processed in an order, where, when a video unit of the multiple video units is processed in the conversion, one or more frequence tables and/or one or more sorted intra prediction mode (IPM) tables are reset or initialized, where the one or more frequence tables include information about frequence of one or more intra prediction modes used for processing previous video units in the multiple video units, where the previous video units precede in time the video unit, where the frequence indicates an occurrence of the one or more intra prediction modes used for the conversion, and where the one or more sorted IPM tables indicate the one or more intra prediction modes used in the processing.

Abstract: A method implemented by a video coding apparatus. The method includes applying a first filter to an unfiltered sample of a video unit to generate a filtered sample. The first filter is a neural network (NN) filter based on a non-deep learning-based filter (NDLF) being disabled, and the first filter is the NDLF based on the NN filter being disabled. The method also includes performing a conversion between a video media file and a bitstream based on the filtered sample that was generated.

Abstract: A video processing method includes performing a conversion between a video including a video unit and a coded representation of the video, where, after the video unit is encoded or decoded with an intra prediction mode, one or more frequence tables and/or one or more sorted intra prediction mode (IPM) tables are selectively updated according to a rule, where the one or more frequence tables include information about frequence of the intra prediction mode used for processing the video unit in the conversion, where the frequence indicates an occurrence of the intra prediction mode used for the conversion, and where the one or more sorted IPM tables indicate the intra prediction mode used in the processing.

Abstract: A method for processing video data is disclosed. The method includes: performing a conversion between visual media data and a bitstream of the visual media data by an image compression framework, wherein the image compression framework includes a preprocessing function and a compressor, and the visual media data is processed by the preprocessing function and the compressor sequentially, and wherein the preprocessing function receives a first image among the visual media data with a size of W0×H0×C0 as input and outputs a preprocessed first image with a size of W1×H1×C1, wherein W0 is an input width, H0 is an input height, and C0 is an input channel number, and wherein W1 is an output width, H1 is an output height, and C1 is an output channel number.
