Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: applying, for a conversion between a video unit of a video and a bitstream of the video, a connection to a plurality of filters; applying the plurality of filters with the connection in combination to the video unit; and performing the conversion based on the filtered video unit.

Abstract: A mechanism for processing video data is disclosed. A determination is made to resize an image with a first size to create a resized image with a second size. A conversion is performed between a visual media data and a bitstream based on the resized image. The conversion includes applying a neural network-based coding model to the resized image to achieve variable rate neural network-based compression.

Abstract: Embodiments of the present disclosure provide a solution for data processing. A method for data processing is proposed. The method comprises: determining, by using a first model with an attention mechanism during a conversion between data and a bitstream of the data, a probability distribution for entropy coding associated with the bitstream; and performing the conversion based on the probability distribution.

Abstract: A method of processing video data. The method includes down-sampling a video unit of a video prior to application of a super resolution (SR) process and performing a conversion between the video including the video unit and a bitstream of the video based on the video unit as down-sampled. A corresponding video coding apparatus and non-transitory computer-readable recording medium are also disclosed.
