Method and Apparatus of Adaptive Interpolation Filtering in Video Coding System

Abstract

A method and apparatus adaptive interpolation filtering are disclosed. According to the method, input data comprising a current block or subblock are received, wherein the input data correspond to pixel data to be encoded at a video encoder side or the input data correspond to a coded data to be decoded at a video decoder side, and wherein the current block or subblock is coded in an intra mode, inter mode, or non-intra mode. An interpolation filter list comprising multiple interpolation filters is determined. The multiple interpolation filters in the interpolation filter list are reordered to form a reordered interpolation filter list. A target interpolation filter is selected from the reordered interpolation filter list. The target interpolation filter is applied to the current block or subblock to generate an interpolated block or subblock. The interpolated block or subblock is provided.

Dependencies are inferred from the claim text.
