An Multi-Mini-Partition Intra Block Copying for Screen Content Coding
Liping Zhao, Tao Lin · 2015
In this paper, an multi-mini-partition intra block copying (MMPIBC) coding technique for screen contents is presented.In MMPIBC coder, a Coding Unit(CU) with size 8x8 is firstly broken into multiple mini-partitions.Each mini-partition of CU separately select the displacement vector(DV) with the same search range.To further decrease the RD-cost of MMPIBC mode, DV predictor and pseudo three planar search techniques are applied to get more coding gain.Experiments show that for some types of screen contents, the average Bit-rate saving of MMPIBC achieves up to 14.9%.
