In HEVC, a total of 35 intra prediction modes are defined such as planar, DC, and 33 angular modes. Substitution process applied to unavailable reference samples causes degradation of prediction accuracy. To improve the accuracy, we propose a modification of processing order of divided transform blocks according to intra prediction mode. Our proposal reduces the substitution process and enable to refer immediately below/right neighboring samples as reference samples where HEVC cannot refer. Simulation results show improvement of coding efficiency with slight encoder and decoder run time. |
