Abstract: Disclosed is a mechanism for selecting an interpolation filter for use in conjunction with an affine block in video coding. A motion vector is determined for a sub-block of the affine block based on control points. A sub-block size of the sub-block is also determined. The interpolation filter is selected for application to a reference block corresponding to the sub-block. The interpolation filter is selected based on the sub-block size. The motion vector of the sub-block and an offset of a current sample of the sub-block are employed to determine a reference sample at the reference block. This includes applying the interpolation filter to the reference block to determine the reference sample when the motion vector at the offset points to a fractional position at the reference block. The reference samples are employed to determine residual information in order to encode the affine block.

Abstract: A system and method of reducing blocking artifacts and providing enhanced coding efficiency based, as least in part, upon evaluation of relative smoothness of signals at a coding boundary. In some embodiments, a boundary threshold difference can be established beyond which it is determined that the difference is representative of a natural or intended boundary and filtering can be applied to those boundaries having differences below the boundary threshold difference. In some further embodiments, the ramps of the signal across the boundary can be evaluated to determine whether weak or strong filtering might be appropriate. In some further embodiments, weak filtering can be performed that reduces blocking artifacts, improves coding efficiency, but does not distort ramp signals across the boundary.

Abstract: A method of video decoding for a decoder is provided. In the method, prediction information of a current block in a current picture is decoded from a coded video bitstream, where the prediction information is indicative of an inter prediction mode.

A primary transform is thus performed for a transform block according to a pre-defined primary transform type based on that the filtering process is determined to be applied on the current block, where the transform block is partitioned from the current block.

Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. An apparatus for video decoding includes processing circuitry. The processing circuitry checks an inferable condition for a flag of a specific prediction mode for a current block before parsing the flag of the specific prediction mode for the current block from a coded video bitstream. The specific prediction mode is one of a plurality of inter picture prediction modes. When the inferable condition indicates that the flag is inferable, the processing circuitry infers the flag without parsing the flag from the coded video bitstream. When the inferable condition indicates uncertainty for inferring the flag, the processing circuitry parses the flag from the coded video bitstream. Then, the processing circuitry reconstructs the current block according to the specific prediction mode when the flag is indicative of an application of the specific prediction mode on the current block.
