CE3-related: Interpolation filtering for intra-prediction within rectangular blocks
Abstract
In CE3 [1], different intra-interpolation filters were considered to improve the coding efficiency of intra prediction for skew directional modes. In this contribution, we propose an alternative mechanism of selecting interpolation filters. On top of VTM, the simulation results for this technique reportedly show - 0.60%, - 0.44% and - 0.52% BD-rate savings on Y, Cb and Cr components respectively for All Intra (AI) configuration with 105% encoding time and appr. 100% decoding time on average.

In CE3, different intra-interpolation filters were considered to improve the coding efficiency of intra prediction for skew directional modes. This contribution proposes an alternative mechanism of selecting interpolation filters. On top of the VTM, the simulation results for this technique reportedly show 0.60%for the AI configuration with 105% encoding time and 100% decoding time on average.
This scheme would add several filters. It is a variation of a scheme tested in CE3. Further study was encouraged.
