Purpose of review The discovery of a new class of intrinsically photosensitive retinal ganglion cells (ipRGCs) revealed their superior role for various nonvisual biological functions, including the pupil light reflex, and circadian photoentrainment. Recent ...
Attention is crucial for visual perception because it allows the visual system to effectively use its limited resources by selecting behaviorally and cognitively relevant stimuli from the large amount of information impinging on the eyes. Reflexive, stimul ...
This research project deals with the suitability of the program Radiance for detailing the spectral qualities of the light received inside a room. More specifically, it asks whether Radiance’s innate RGB algorithm can be used to accurately determine the no ...
This paper proposes a novel approach for the analysis of illicit tablets based on their visual characteristics. In particular, the paper concentrates on the problem of ecstasy pill seizure profiling and monitoring. The presented method extracts the visual ...
In the field of surgical robotics, it is difficult to find objective assessment techniques for evaluating telepresence. In this study we try to merge the concepts from cognitive neuroscience more specifically from the field of tool incorporation (embodimen ...
Perceptual learning is usually very specific. For example, performance improves when observers train with a vertical bisection stimulus. However, this improvement does not transfer to a horizontal bisection stimulus. Here, we show that perceptual learning ...
PURPOSE. Nonvisual light-dependent functions in humans are conveyed mainly by intrinsically photosensitive retinal ganglion cells, which express melanopsin as photopigment. We aimed to identify the effects of circadian phase and sleepiness across 24 hours ...

Indoor scenes are characterized by a high intra-class variability, mainly due to the intrinsic variety of the objects in them, and to the drastic image variations due to (even small) view-point changes. One of the main trends in the literature has been to ...
In sighted humans, light intensity, timing, exposure duration, and spectral composition of light are important to entrain the endogenous circadian pacemaker to the 24-h day-night cycle. We tested the impact of two realistic office lighting conditions durin ...
Within the last decades it became evident that light through the eyes is essential for both visual and non-visual functions. One of the most important non-visual functions of light is the daily entrainment of the circadian clock by environmental light cond ...
