Adaptive inter CU partitioning based on a look-ahead stage for HEVC

作者:

Highlights:

• A look-ahead stage calculates preliminary motion-based costs on a block basis.

• The proposed approach estimates the optimal CTU/CU splitting and mode decisions.

• Low-complexity method that delivers competitive time savings and coding efficiency.

• Valuable for other applications at no additional cost, e.g. rate control.
