Abstract: An apparatus and a method for image coding with asymmetric partitioning are disclosed. Instead of a conventional approach of using partitioning mechanisms such as QTBT and Multi-Type Tree (MTT), an asymmetric partitioning mechanism that can provide a good performance/complexity tradeoff is introduced. This allows constraining parameters of the asymmetric partitioning mechanism to exclude modes that appear not frequently, thereby allowing keeping encoder-side complexity low and avoiding signaling overhead.
