This contribution proposes a history-based merge candidate for intra merge mode. The intra merge mode is tested as EE2-2.5 in this meeting, which constructs an intra merge candidate list by adding intra modes used in intra-coded neighboring blocks and select a merge candidate to predict the current block. To derive five intra merge candidates of the list, EE2-2.5a extends the number of checks for non-adjacent spatial merge candidates from 18 of ECM-13.0 to 87, whereas EE2-2.25c maintains the same number as ECM-13.0. To avoid the vast of checking non-adjacent spatial merge candidates in EE2-2.25a, it is proposed that history-based merge candidates are alternatively introduced in EE2-2.5c. A maximum of five history-based merge candidates are added to the history buffer and inserted to the intra merge candidate lists when the list is vacant after deriving non-adjacent spatial merge candidates.
