EE2-3.2: LFNST/NSPT set derivation for CCP coded block
Abstract
This contribution reports the results for EE2-3.2. In EE2-3.2, a new method to derive the transform set for intra chroma blocks coded with LFNST/NSPT and CCP mode is proposed, which was initially proposed in JVET-AJ0086. This test uses the DIMD method to derive a traditional intra prediction mode based on the prediction samples, and the LFNST/NSPT transform set is then determined according to the derived intra mode. The impact on coding efficiency and runtimes over ECM-15.0 is reported as {Y, U, V, EncT, DecT} below:
