HEVC based Stereo Video codec [PDF]
2nd IET International Conference on Intelligent Signal Processing 2015 (ISP), 2015 Development of stereo video codecs in latest multi-view extension of HEVC (MV-HEVC) with higher compression efficiency has been an active area of research. In this paper, a frame interleaved stereo video coding scheme based on MVHEVC standard codec is proposed.

Division-Free Multiquantization Scheme for Modern Video Codecs
Advances in Multimedia, 2012 The current trend of digital convergence leads to the need of the video encoder/decoder (codec) that should support multiple video standards on a single platform as it is expensive to use dedicated video codec chip for each standard. The paper presents a

Codec-Aware Video Delivery Over SDNs
, 2021 To guarantee quality of delivery for video streaming over software defined networks, efficient predictors and adaptive routing frameworks are required. We demonstrate an agent that predicts video quality of delivery metrics in a scalable way using a bespoke codec-aware learning model.

Zerotree-based stereoscopic video CODEC [PDF]
Optical Engineering, 2005 Due to the provision of a more natural representation of a scene in the form of left and right eye views, a stereoscopic imaging system provides a more effective method for image/video display. Unfortunately the vast amount of information that must be transmitted/stored to represent a stereo image pair/video sequence, has so far hindered its use in ...

Motion Compensation on DCT Domain
EURASIP Journal on Advances in Signal Processing, 2001 Alternative fully DCT-based video codec architectures have been proposed in the past to address the shortcomings of the conventional hybrid motion compensated DCT video codec structures traditionally chosen as the basis of implementation of standard ...

A Novel H.264/AVC Based Multi-View Video Coding Scheme [PDF]
, 2008 This paper investigates extensions of H.264/AVC for compressing multi-view video sequences. The proposed technique re-sorts frames of sequences captured by multiple cameras looking at a person in a scene from different views and generates a single video ...

Flow-Process Foreground Region of Interest Detection Method for Video Codecs
IEEE Access, 2017 Detecting the foreground region of interest (ROI) for video sequences is an important issue both for video codecs and monitoring systems. In this paper, we propose a flow-process-based method to detect foreground ROI using four steps: global motion ...
