Predicting Split Decisions in MPEG-2 to HEVC Video Transcoding
This paper proposes learning-based approaches for transcoding MPEG-2 video into HEVC. In the training mode of the transcoder, mappings between extracted features and split decisions are calculated. While in the transcoding ...
Recursive Quad-Tree Block Partitioning for Data Embedding in Images
In this paper, we propose to embed messages in raw images using a recursive block partitioning technique adopted from HEVC video coding technology. This work introduces a quad-tree partitioning solution in which square ...
Detecting Double and Triple Compression in HEVC Videos Using the Same Bit Rate
Digital video forensics refers to the process of analysing, examining, evaluating and comparing a video for use in legal matters. In digital video forensics, the main aim is to detect and identify video forgery to ensure ...
