Homogeneous light stimulation of melanopsin and cones with a Maxwellian view device for the human eye

Gilles Evéquoz, Patrick Robert Flückiger

We designed and tested a device to stimulate specifically one photoreceptor type, or a combination of some of them, of the human eye by using up to six primaries. The device produces a homogeneous light field over 40 degrees which is projected onto the ret ...

MRI-based brain volumetry and retinal optical coherence tomography as the biomarkers of outcome in acute methanol poisoning

Tobias Kober, Bénédicte Marie Maréchal

Background: Basal ganglia lesions are typical findings on magnetic resonance imaging (MRI) of the brain in survivors of acute methanol poisoning. However, no data are available on the association between the magnitude of damaged brain regions, serum concen ...

Reciprocal Collision Avoidance For Quadrotors Using On-board Visual Detection

Denis Gillet, Alcherio Martinoli, Steven Adriaan Roelofsen

In this paper we present a collision avoidance system based on visual detection. Our hardware consists of a Hummingbird quadrotor equipped with a large red marker with two built-in fish-eye cameras. Fusion of the measurements from the two cameras is done u ...

Visual Mapping of Internal Pipe Walls using Sparse Features for Application on board Autonomous Underwater Vehicles

Adrian Bodenmann

In this project an algorithm to generate a single image of an entire water pipe's inside wall was developed. An Autonomous Underwater Vehicle (AUV) equipped with a fish-eye camera will be deployed to dive through the pipe and take pictures of its inside wa ...

Frequency encoded assessment of retinal physiology

Theo Lasser, Adrian Bachmann, Rainer Leitgeb, Roland Michaely, Cédric Blatter

We demonstrate in-vivo functional imaging of the human retina with Fourier domain optical coherence tomography employing frequency encoding of an excitation pattern. The principle is based on projecting a modulated rectangular pattern across the foveal reg ...

Omnidirectional Active Vision for Evolutionary Car Driving

Dario Floreano, Mototaka Suzuki, Jacob Van der Blij

We describe a set of simulations to evolve omnidirectional active vision, an artificial retina scanning over images taken via an omnidirectional camera, being applied to a car driving task. While the retina can immediately access features in any direction, ...
