Statistical analysis of Post-HEVC encoded videos

The Post-HEVC is the emerging video coding standard beyond the High Efficiency Video Coding (HEVC) standard. It is more complex in transformation and prediction steps but it offers the opportunity of 3D and 360° videos coding and compression. This paper presents different statistical analyzes of Post-HEVC encoded videos especially analysis on 1D and 2D transformation types and analysis on intra and inter prediction types of some test videos for different classes and resolutions. Analyzes are carried out at the decoder level where the coding decision has already been taken by the encoder. Results show that the choice of transformation (type and size) and the prediction type (intra or inter) depends on the nature of video: motion and texture. This work can be considered as a milestone for proposing intelligent algorithms based on video characteristics to perform fast decision in the Post-HEVC encoding process.
