JVET-AK0152 AHG9: On Spatial Extrapolation for NNPF [S. Deshpande (Sharp), M. M. Hannuksela (Nokia)]

Consideration of this was chaired by H. Tan on 15 January 2025 at 1237.

Corner cases related to patch-wise operation when using spatial extrapolation are identified and equations related to those are proposed to be modified. This aspect has been captured in the Editor’s note and it is asserted that the proposed modifications help to resolve the Editor’s note.

Two corner cases were identified in the VSEI v4 draft.

The proposed change is to check corner case first and then the common case in the “else” part.

Decision (BF): Adopt.
