A method and system for encoding and decoding avatar animation data are disclosed. Source avatar parameters, including skeletal, morph, blendshape or keypoint parameters, are mapped to corresponding target avatar parameters according to correspondence information. The mapped parameters and source parameters are encoded in a data stream comprising avatar animation units (AAUs), each with a header and payload. Configuration AAUs signal profile, timescale and correspondence indices. Control, morph, joint and keypoint AAUs carry animation data. The data stream enables efficient cross-platform transmission of avatar animation, and decoding generates and renders target avatar meshes with synchronized animation.

Methods and apparatuses for video coding and decoding are provided. The method of video encoding includes accessing a reconstructed block corresponding to a block in a picture of a video, determining at least one filter pattern based on a property of the block and filtering the reconstructed block according to the at least one filter pattern. The method of video decoding includes accessing a reconstructed block corresponding to a block in a picture of an encoded video, determining at least one filter pattern based on a property of the block and filtering the reconstructed block according to the at least one filter pattern. A bitstream formatted to include encoded data, a computer-readable storage medium and a computer program product are also described.

A neural processing unit (NPU) for decoding video or feature map is provided. The NPU may comprise at least one processing element (PE) to perform an inference using an artificial neural network. The at least one PE may be configured to receive and decode data included in a bitstream. The data included in the bitstream may comprise data of a base layer. Alternatively, the data included in the bitstream may comprise data of the base layer and data of at least one enhancement layer. The data of the base layer included in the bitstream may include a first feature map. The data of the at least one enhancement layer included in the bitstream may include a second feature map.

Methods and apparatuses for video coding and decoding are provided. The method of video encoding includes determining a set of parameters for illumination compensation associated with a first motion compensated reference block of a block in a picture of a video based on a function of a set of samples of the first motion compensated reference block and a set of samples of a second motion compensated reference block of the block, processing a prediction of the block based on the set of parameters, the prediction being associated with the first motion compensated reference block and encoding the block based on the processed prediction. A bitstream formatted to include encoded data, a computer-readable storage medium and a computer program product are also described.
