Abstract

Systems, methods, and instrumentalities are configured for transform derivation using decoder-side intra mode derivation (DIMD) for one or more of template-based intra mode derivation (TIMD) mode or DIMD mode. In examples, a video coding device may be configured to determine that a template-based intra mode derivation (TIMD) mode is enabled for a current block. The device may apply a decoder side intra mode derivation (DIMD) like process to derive a virtual intra prediction mode (VIPM) from a neighboring reconstructed template of a current block or a prediction block associated with the current block. The device may, based on the derived VIPM, determine a transform kernel set for predicted residual coding.
