N2 - Non-rectangular block partitioning is a well-known method for improved inter-picture prediction in video coding, enabling better spatial adaptation to the signal properties. This contribution presents the most recent proposal of geometric inter-prediction (GIP) made to the Versatile Video Coding (VVC) standardization activity led by the Joint Video Experts Team (JVET). Implemented in the latest test model VTM-5.0 and evaluated according to the JVET Common Test Conditions, the proposed low-complexity GIP scheme provides objective luma BD-rate reductions of 0.22 % for random access and 0.44 % for low-delay test cases at 7% encoder runtime increase and negligible decoder runtime increase. The coding gain is provided by non-triangular partitioned blocks and in the presence of multiple other VVC coding tools. Furthermore, BD-rate reductions of 2.58 % and 2.78 % can be achieved specifically for pure screen content by employing an adaptive blending filter.
