Markov Decision Process Based Energy-Efficient On-Line Scheduling for Slice Parallel Video Decoders on Multicore Systems
Pascal Frossard, David Atienza Alonso, Karim Kanoun
We consider the problem of energy-efficient on-line scheduling for slice-parallel video decoders on multicore systems. We assume that each of the processors are Dynamic Voltage Frequency Scaling (DVFS) enabled such that they can independently trade off per ...
Ieee-Inst Electrical Electronics Engineers Inc2013User-Action-Driven View and Rate Scalable Multiview Video Coding
We derive an optimization framework for joint view and rate scalable coding of multi-view video content represented in the texture plus depth format. The optimization enables the sender to select the subset of coded views and their encoding rates such that ...
Ieee-Inst Electrical Electronics Engineers Inc2013Benchmarking of quality metrics on ultra-high definition video sequences
Touradj Ebrahimi, Philippe Hanhart
The performance of objective quality metrics for high-definition (HD) video sequences is well studied, but little is known about their performance for ultra-high definition (UHD) video sequences. This paper analyzes the performance of several common object ...
2013Quality Assessment of a Stereo Pair Formed From Two Synthesized Views Using Objective Metrics
Touradj Ebrahimi, Philippe Hanhart
When a stereo pair is formed from two synthesized views, it is unclear whether objective 2D quality metrics can provide a good estimation of the perceived quality. In this paper, this problem is addressed considering a 3D video represented in multiview vid ...
2013A Parallelized Layered QC-LDPC Decoder for IEEE 802.11ad
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Alessandro Cevrero, Nicholas Alexander Preyss
We present a doubly parallelized layered quasi-cyclic low density parity-check decoder for the emerging IEEE 802.11ad multigigabit wireless standard. The decoding algorithm is equivalent to a nonparallelized layered decoder and, thus, retains its favorable ...
IEEE2013Dataflow Program Analysis and Refactoring Techniques for Design Space Exploration: MPEG-4 AVC/H.264 Decoder Implementation Case Study
Marco Mattavelli, Simone Casale Brunet, Claudio Paolo Alberti, Ab Al Hadi Bin Ab Rahman
This paper presents a methodology to perform design space exploration of complex signal processing systems implemented using the CAL dataflow language. In the course of space exploration, critical path in dataflow programs is first presented, and then anal ...
2013Consistent view synthesis in interactive multiview imaging
Pascal Frossard, Thomas Maugey
An important question in the design of interactive multiview systems consists in determining the information needed by the decoder for high quality navigation between the views. Most of the existing techniques focus on the captured sequences and only consi ...
