Abstract
Methods and apparatus for video coding are disclosed. According to one method, a selected set of angular intra prediction candidate modes corresponding to a subset of an initial set of angular intra prediction modes is used to derive DIMD candidates. In another method, a delta angle between the final intra prediction mode and a DIMD derived mode is signalled or parsed. In yet another method, a DIMD candidate mode is determined by using a process including comparing gradient magnitudes of the gradient filtered results with a threshold.
