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 ...
A regression-based framework for estimating the objective quality of HEVC coding units and video frames
A no-reference objective quality estimation framework is proposed. The framework is suitable for any block-based video codec. In the proposed solution, features are extracted from coding units and summarized to form features ...
MPEG-2 to HEVC Video Transcoding With Content-Based Modeling
This paper proposes an efficient MPEG-2 to HEVC video transcoder. The objective of the transcoder is to migrate the abundant MPEG-2 video content to the emerging HEVC video coding standard. The transcoder introduces a ...
H.264/AVC Motion Vector Concealment Solutions Using Online and Offline Polynomial Regression
This paper introduces two polynomial regression solutions for error concealment by predicting the values of motion vectors of lost macroblocks. The two solutions are online and offline polynomial regression modeling. In ...
