Abstract: Aspects of the disclosure provide a method and an apparatus including processing circuitry for video decoding. The processing circuitry can decode coded information of a coding block in a picture of a coded video sequence. The coded information can indicate a clipping index m that indicates a clipping value for a filter that is applied to the coding block.

The first function is dependent on a bit depth B and is independent of the clipping index m, and the second function is dependent on the clipping index m and is independent of the bit depth B. The processing circuitry can generate a filtered coding block by applying the filter corresponding to the clipping value to the coding block.

The template parameters that are not included in the subset are not received by the receiver.

Abstract: In omnidirectional videos, a straight line in the rendering space may no longer appear as a straight line in the frame to be encoded, due to the projection between the encoding space and the rendering space. To adapt to the geometry of omnidirectional videos, intra prediction is performed along non-straight curves. In particular, references samples in neighboring reconstructed blocks of a current block are copied along non-straight curves to form a predicted block for the current block. The non-straight curves may be computed online based on a single intra prediction directional mode for the current block. The parameters of non-straight curves may be based on the mapping used in forming the omnidirectional videos, and the location/size of the current block. The non-straight curves may be obtained using a look-up table or an analytical function that is dependent on the location and size of the current block.
