Most frequent mode for intra-mode coding in video coding

The emerging versatile video coding (VVC) standard currently adopts 67 intra-prediction modes in order to improve the intra-prediction performance. The most probable mode (MPM) is used in video coding to encode the prediction mode efficiently based on the modes of the neighbouring blocks. Due to an increase in the number of intra-modes and increase in the resolution of the input sequence, it is ne...
