A fully organic retinal prosthesis restores vision in a rat model of degenerative blindness

Diego Ghezzi

The degeneration of photoreceptors in the retina is one of the major causes of adult blindness in humans. Unfortunately, no effective clinical treatments exist for the majority of retinal degenerative disorders. Here we report on the fabrication and functi ...

The multisensory function of the human primary visual cortex

Roberto Martuzzi, Antonia Thelen

It has been nearly 10 years since Ghazanfar and Schroeder (2006) proposed that the neocortex is essentially multisensory in nature. However, it is only recently that sufficient and hard evidence that supports this proposal has accrued. We review evidence t ...

Retinotopic encoding of the Ternus-Pikler display reflected in the early visual areas

Michael Herzog, Wietske Van der Zwaag, Gijs Plomp, Yvonne Evelina Thunell

The visual representation of the world is often assumed to be retinotopic, and many visual brain areas are indeed organized retinotopically. Visual perception, however, is not based on a reference frame anchored in retinotopic coordinates. For example, whe ...

EUMSSI team at the MediaEval Person Discovery Challenge 2016

Jean-Marc Odobez

We present the results of the EUMSSI team’s participation in the Multimodal Person Discovery task. The goal is to identify all people who simultaneously appear and speak in a video corpus. In the proposed system, besides improving each modality, we emphasi ...

What crowding can tell us about object representations

Michael Herzog, Aaron Michael Clarke, Mauro Manassi

In crowding, perception of a target usually deteriorates when flanking elements are presented next to the target. Surprisingly, adding further flankers can lead to a release from crowding. In previous work we showed that, for example, vernier offset discri ...

Visual Link Retrieval in a Database of Paintings

Frédéric Kaplan, Isabella Di Lenardo, Benoît Laurent Auguste Seguin, Carlotta Striolo

This paper examines how far state-of-the-art machine vision algorithms can be used to retrieve common visual patterns shared by series of paintings. The research of such visual patterns, central to Art History Research, is challenging because of the divers ...

Two lectures about representing scientific communities by data visualization

Dario Rodighiero

These lectures present a research that investigates the representation of communities, and the way to foster their understanding by different audiences. Communities are complex multidimensional entities intrinsically difficult to represent synthetically ...

Crowding and shape representations

Michael Herzog, Aaron Michael Clarke, Mauro Manassi

In crowding, target perception deteriorates when flanking elements are added. Crowding is traditionally characterized by target-flanker interactions which are (1) deleterious, (2) spatially confined within Bouma’s window, and (3) feature specific. Here, we ...

Facial blindsight

Marco Solcà

Blindsight denotes unconscious residual visual capacities in the context of an inability to consciously recollect or identify visual information. It has been described for color and shape discrimination, movement or facial emotion recognition. The present ...

Contour-integration deficits in intact visual field of hemianopia patients

Michael Herzog, Ophélie Gladys Favrod

We investigated Gestalt perception in the intact visual field (VF) of hemianopia patients. Three patients and matched controls performed a Yes-No figure detection task. Gabor patches of one orientation, making up the outline of a square, were embedded in r ...
