H2B2VS (HEVC Hybrid Broadcast Broadband Video Services) – building innovative solutions over hybrid networks

Claudio Paolo Alberti

Broadcast and broadband networks continue to be separate worlds in the video consumption business. Some initiatives such as HbbTV have built a bridge between both worlds, but its application is almost limited to providing links over the broadcast channel t ...

Brillouin distributed fiber sensing at ultra-high spatial resolution

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Andrey Denisov

Sophisticated techniques have been recently developed to achieve centimetric spatial resolution in distributed Brillouin fibre sensing, by-passing the slow response of this optoacoustic interaction by creating a localized stationary material vibration. Mor ...

FASA: Fast, Accurate, and Size-Aware Salient Object Detection

Sabine Süsstrunk, Gökhan Yildirim

Fast and accurate salient-object detectors are important for various image processing and computer vision applications, such as adaptive compression and object segmentation. It is also desirable to have a detector that is aware of the position and the size ...

Extension of ultrasound Fourier slice Imaging theory to sectorial acquisition

Jean-Philippe Thiran, Rafael Eduardo Carrillo Rangel, Olivier Bernard, Adrien Georges Jean Besson

Ultrasound image reconstruction from the echoes received by an ultrasound probe after the transmission of diverging waves is an active area of research because of its capacity to insonify at ultra-high frame rate with large regions of interest using small ...

Subjective and objective evaluation of HDR video compression

Touradj Ebrahimi, Philippe Hanhart, Martin Rerabek

Recent efforts by MPEG and research community to standardize high dynamic range (HDR) video compression require efficient objective metrics. This paper investigates how well the currently available metrics measure perceptual quality of HDR video. For this ...

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 ...

Ultra-Eye: UHD and HD images eye tracking dataset

Touradj Ebrahimi, Philippe Hanhart, Hiromi Nemoto

Due to the recent advances in ultra high definition (UHD) displays, UHD TV may replace HD TV in a near future. However, little is known about the effect of UHD content on human visual perception, specifically, on human visual attention, viewing strategies, ...

Exploring MPEG HEVC decoder parallelism for the efficient porting onto many-core platforms

Marco Mattavelli, Simone Casale Brunet, Claudio Paolo Alberti, Damien Jack De Saint Jorre

MPEG High Efficient Video Coding (HEVC) is likely to emerge as the video coding standard for HD and Ultra-HD TV resolutions. The two elements that push HEVC beyond the previous standards are a higher compression efficiency of about a factor of two, and the ...
