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

Patrick Robert Flückiger, Gilles Evéquoz

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 ...

Pupil responses derived from outer and inner retinal photo reception are normal in patients with hereditary optic neuropathy

Mirjam Münch

We compared the pupil responses originating from outer versus inner retinal photoreception between patients with isolated hereditary optic neuropathy (HON, n = 8) and healthy controls (n = 8). Three different testing protocols were used. For the first two ...

Miniature curved artificial compound eyes

Dario Floreano, Ramon Pericet Camara, Michal Karol Dobrzynski, Géraud L'Eplattenier

In most animal species, vision is mediated by compound eyes, which offer lower resolution than vertebrate single-lens eyes, but significantly larger fields of view with negligible distortion and spherical aberration, and high temporal resolution in a tiny ...

Clinical and genetic investigation of a large Tunisian family with complete achromatopsia: identification of a new nonsense mutation in GNAT2 gene

Complete achromatopsia is a rare autosomal recessive disease associated with CNGA3, CNGB3, GNAT2 and PDE6C mutations. This retinal disorder is characterized by complete loss of color discrimination due to the absence or alteration of the cones function. Th ...

Repairing Gamut Problems in CIECAM02: A Progress Report

Sabine Süsstrunk

The color-appearance model CIECAM02 has several problems, which can result in mathematical instabilities, due to the relation of the chromatic-adaptation primaries to the spectrum locus and to the presumed physiological cone primaries. To keep a correspond ...

A Model of Retinal Local Adaptation for the Tone Mapping of Color Filter Array Images

Sabine Süsstrunk, Laurence Meylan

We present a tone mapping algorithm that is derived from a model of retinal processing. Our approach has two major improvements over existing methods. First, tone mapping is applied directly on the mosaic image captured by the sensor, analogue to the human ...

Evolutionary Active Vision Toward Three Dimensional Landmark-Navigation

Dario Floreano, Mototaka Suzuki

Active vision may be useful to perform landmark-based navigation where landmark relationship requires active scanning of the environment. In this article we explore this hypothesis by evolving the neural system controlling vision and behavior of a mobile r ...
