Broadcasting oneself: Visual Discovery of Vlogging Styles

Daniel Gatica-Perez, Oya Aran, Joan Isaac Biel Tres

We present a data-driven approach to discover different styles that people use to present themselves in online video blogging (vlogging). By vlogging style, we denote the combination of conscious and unconscious choices that the vlogger made during the pro ...

3D Poisson Microscopy Deconvolution With Hessian Schatten-Norm Regularization

Michaël Unser, Stamatios Lefkimmiatis

Inverse problems with shot noise arise in many modern biomedical imaging applications. The main challenge is to obtain an estimate of the underlying specimen from measurements corrupted by Poisson noise. In this work, we propose an efficient framework for ...

PANOPTIC An Interconnected Network of Cameras

Kerem Seyid

Multi-camera systems have attracted attention in recent years due to rapidly dropping cost of digital cameras. This has enabled wide variety of new research topics and applications for Multi View Imaging (MVI) systems. Virtual view synthesis, high performa ...

Visual spatiotemporal processing in the elderly

Michael Herzog

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 ...

Quasi-Static Scheduling of CAL Actor Networks for Reconfigurable Video Coding

Marco Mattavelli, Christophe Lucarz, Jani Boutellier

The upcoming Reconﬁgurable Video Coding (RVC) standard from MPEG (ISO / IEC SC29WG11) deﬁnes a library of coding tools to specify existing or new compressed video formats and decoders. The coding tool library has been written in a dataﬂow/actor- oriented l ...

Daylight illuminant retrieval using redundant image elements

Sabine Süsstrunk, Joanna Marguier

We present a method for retrieving illuminant spectra from a set of images taken with a fixed location camera, such as a surveillance or panoramic one. In these images, there will be significant changes in lighting conditions and scene content, but there w ...

Shot noise, refractive index tomography and aberrations estimation in digital holographic microscopy

Florian Charrière

The present thesis develops some specific aspects of digital holographic microscopy (DHM), namely the effect of shot noise on the phase image accuracy, the use of DHM in micro-tomography and in aberrations evaluation of a microscope objective (MO). DHM is ...
