H.264/AVC to HEVC Video Transcoder Based on Dynamic Thresholding and Content Modeling
The new video coding standard, HEVC, was developed to succeed the current standard, H.264/AVC, as the state of the art in video compression. However, there is a lot of legacy content encoded with H.264/AVC. This paper ...
Altering Split Decisions of Coding Units for Message Embedding in HEVC
This paper proposes a novel message embedding solution based on modifying the split decisions of HEVC videos. The encoder starts by computing a mapping between the split decisions of a Coding Unit (CU) and its features ...
Saliency detection in MPEG and HEVC video using intra-frame and inter-frame distances
This paper proposes a video saliency detection model for MPEG and HEVC coded videos. The model extracts features from MPEG macro blocks and HEVC coding units. The feature variables are based on syntax elements and statistics ...
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 ...
