Audiovisual focus of attention and its application to Ultra High Definition video compression

Touradj Ebrahimi, Martin Rerabek, Jong Seok Lee, Hiromi Nemoto

Using Focus of Attention (FoA) as a perceptual process in image and video compression belongs to well-known approaches to increase coding efficiency. It has been shown that foveated coding, when compression quality varies across the image according to regi ...

Real-time, high-speed video decompression using a frame- and event-based DAVIS sensor

Dynamic and active pixel vision sensors (DAVISs) are a new type of sensor that combine a frame-based intensity readout with an event-based temporal contrast readout. This paper demonstrates that these sensors inherently perform high-speed, video compressio ...

Impact of Ultra High Definition on Visual Attention

Touradj Ebrahimi, Philippe Hanhart, Hiromi Nemoto

Ultra high definition (UHD) TV is rapidly replacing high definition (HD) TV but little is known of its effects on human visual attention. However, a clear understanding of this effect is important, since accurate models, evaluation methodologies, and metri ...

Compression Performance Analysis in HEVC

Touradj Ebrahimi, Philippe Hanhart

In this chapter, performance analysis of HEVC (Recommendation ITU-T H.265 | ISO/IEC 23008-2) in comparison with AVC (Recommendation ITU-T H.264 | ISO/IEC 14996-10) in terms of both objective as well as subjective quality assessments are given. Because of t ...

Secure Computing with the MPEG RVC Framework

Marco Mattavelli, Richard Thavot, Junaid Jameel Ahmad

Recently, ISO/IEC standardized a dataflow-programming framework called Reconfigurable Video Coding (RVC) for the specification of video codecs. The RVC framework aims at providing the specification of a system at a high abstraction level so that the functi ...

Adaptive Multiview Video Streaming: Challenges and Opportunities

Delivering multiview video content over present packet networks poses multiple challenges. First, the best effort nature of the Internet exposes media packets to variable bandwidth, loss, and delay as they traverse the network. Second, the prediction depen ...

Optimized MVC Prediction Structures for Interactive Multiview Video Streaming

Pascal Frossard, Ana Karina De Abreu Goes

The Multiview Video Coding (MVC) standard efficiently compresses multiview video by considering spatial, temporal and interview correlations. This letter studies the impact of the MVC interview prediction structure on both the transmission and the overall ...

Subjective quality evaluation of the upcoming HEVC video compression standard

Touradj Ebrahimi, Francesca De Simone, Philippe Hanhart, Martin Rerabek

High Efficiency Video Coding (HEVC) is the latest attempt by ISO/MPEG and ITU-T/VCEG to define the next generation compression standard beyond H.264/MPEG-4 Part 10 AVC. One of the major goals of HEVC is to provide efficient compression for resolutions beyo ...

Distributed Compressed Representation of Correlated Image Sets

Vijayaraghavan Thirumalai

Vision sensor networks and video cameras find widespread usage in several applications that rely on effective representation of scenes or analysis of 3D information. These systems usually acquire multiple images of the same 3D scene from different viewpoin ...

Image transform for video coding

Pierre Vandergheynst

A method is disclosed for decomposing a set of even and odd pictures into low-band and high-band pictures respectively in a image decomposing unit, in which the even picture is used by at least two prediction motion compensators on which the output signal ...
