Minkowski space is locally the Noldus limit of Poisson process causets
A Poisson process P-lambda on R-d with causal structure inherited from the the usual Minkowski metric on R-d has a normalised discrete causal distance D-lambda (x, y) given by the height of the longest causal chain normalised by lambda(1/d)c(d). We prove t ...
Iop Publishing Ltd2016Saliency-based Representations and Multi-component Classifiers for Visual Scene Recognition
Visual scene recognition deals with the problem of automatically recognizing the high-level semantic concept describing a given image as a whole, such as the environment in which the scene is occurring (e.g. a mountain), or the event that is taking place ( ...
École Polytechnique Fédérale de Lausanne (EPFL)2014Saliency-based representations and multi-component classifiers for visual scene recognition
Visual scene recognition deals with the problem of automatically recognizing the high-level semantic concept describing a given image as a whole, such as the environment in which the scene is occurring (e.g. a mountain), or the event that is taking place ( ...
EPFL2014On linear and quadratic Lipschitz bounds for twice continuously differentiable functions
Dominique Bonvin, Grégory François, Gene Bunin
Lower and upper bounds for a given function are important in many mathematical and engineering contexts, where they often serve as a base for both analysis and application. In this short paper, we derive piecewise linear and quadratic bounds that are state ...
arXiv:1406.3991 [math.OC]2014Attention Driven Foveated Video Quality Assessment
Contrast sensitivity of the human visual system to visual stimuli can be significantly affected by several mechanisms, e. g., vision foveation and attention. Existing studies on foveation based video quality assessment only take into account static foveati ...
Ieee-Inst Electrical Electronics Engineers Inc2014Sparse Binary Features for Image Classification
In this work a new method for automatic image classification is proposed. It relies on a compact representation of images using sets of sparse binary features. This work first evaluates the Fast Retina Keypoint binary descriptor and proposes imp ...
2013Visual spatiotemporal processing in the elderly
We used backward masking paradigm to investigate the effects of aging on visual spatiotemporal processing. First, thirty-three older (M=65.3 years) and ten younger adults (M=24.3 years) had to indicate the offset direction of a vernier that was masked by a ...
Pion Ltd.2012Cooperative video streaming on smartphones
Christina Fragouli, Lorenzo Keller
Video applications are increasingly popular over smartphones. However, in current cellular systems, the downlink data rate fluctuates and the loss rate can be quite high. We are interested in the scenario where a group of smartphone users, within proximity ...
2011Video Quality for Face Detection, Recognition and Tracking
Many distributed multimedia applications rely on video analysis algorithms for automated video and image processing. Little is known, however, about the minimum video quality required to ensure an accurate performance of these algorithms. In an attempt to ...
2011Balancing Attended and Global Stimuli in Perceived Video Quality Assessment
The visual attention mechanism plays a key role in the human perception system and it has a significant impact on our assessment of perceived video quality. In spite of receiving less attention from the viewers, unattended stimuli can still contribute to t ...
