Subjective quality evaluation of foveated video coding using audio-visual focus of attention

Touradj Ebrahimi, Francesca De Simone, Jong Seok Lee

This paper presents a foveated coding method using audio-visual focus of attention and its evaluation through extensive subjective experiments on both standard definition and high definition sequences. Regarding a sound-emitting region as the location draw ...

Adult Face Recognition in Score-Age-Quality Classification Space

Andrzej Drygajlo, Weifeng Li, Hui Qiu

Face verification in the simultaneous presence of age progression and changing face-image quality is an important problem that has not been widely addressed. In this paper, we study the problem by designing and evaluating a generalized Q-stack model, which ...

A User-Centric Evaluation Framework for Recommender Systems

Pearl Pu Faltings, Li Chen, Rong Hu

This research was motivated by our interest in understanding the criteria for measuring the success of a recommender system from users’ point view. Even though existing work has suggested a wide range of criteria, the consistency and validity of the combin ...

Subjective quality evaluation via paired comparison: application to scalable video coding

Touradj Ebrahimi, Francesca De Simone, Jong Seok Lee

Scalable video coding is a powerful solution for content delivery in many interactive multimedia services due to its adaptability to varying terminal and network constraints. In order to successfully exploit such adaptability, it is necessary to understand ...

Significance Driven Computation on Next-Generation Unreliable Platforms

Vaibhav Gupta, Georgios Karakonstantis

In this paper, we propose a design paradigm for energy efficient and variation-aware operation of next-generation multicore heterogeneous platforms. The main idea behind the proposed approach lies on the observation that not all operations are equally impo ...

Efficient Video Coding based on Audio-Visual Focus of Attention

Touradj Ebrahimi, Francesca De Simone, Jong Seok Lee

This paper proposes an efficient video coding method using audio-visual focus of attention, which is based on the observation that sound-emitting regions in an audio-visual sequence draw viewers' attention. First, an audio-visual source localization algori ...

Impact of flood deposits on earthworm communities in alder forests from a subalpine floodplain (Kandersteg, Switzerland)

Claire Guenat, Géraldine Michèle Bullinger, Jean-Michel Gobat, Renée-Claire Le Bayon

In many ecosystems, bioindication is a tool to estimate biodiversity and quality of environment. In soils,invertebrates are generally suitable bioindicators, especially earthworms. In floodplains, young alluvial soils are exposed to sedimentation and erosi ...

Subjective quality assessment of H.264/AVC video streaming with packet losses

Touradj Ebrahimi, Francesca De Simone, Frédéric Dufaux

Research in the field of video quality assessment relies on the availability of subjective scores, collected by means of experiments in which groups of people are asked to rate the quality of video sequences. The availability of subjective scores is fundam ...
