Evaluating Chromatic Adaptation Transform Performance

The performance of many color science and imaging algorithms are evaluated based on their mean errors. However, if these errors are not normally distributed, statistical evaluations based on the mean are not appropriate performance metrics. We present a no ...

Linear demosaicing inspired by the human visual system

Sabine Süsstrunk

There is an analogy between single-chip color cameras and the human visual system in that these two systems acquire only one limited wavelength sensitivity band per spatial location. We have exploited this analogy, defining a model that characterizes a one ...

The Influence of Luminance on Local Tone Mapping

Sabine Süsstrunk, Laurence Meylan

We study the influence of the choice of color space for local tone mapping methods. Many local tone mapping methods do not perform well when applied independently to the three color channels of an RGB image. A common solution is to only treat the luminance ...

Data coding tools for color-coded vector nanolithography

Andrzej Kulik, Charles Baur, Sébastien Grange, Raphaël Foschia, Saveen Kumar

We propose and demonstrate the ability and efficiency of using a universal file format for a nanolithography pattern. A problem faced by the physicists working in the field of nanolithography is a lack of a flexible pattern design software (possibly open–s ...

Splitting of the recombination zone in organic light emitting diodes by dye doping

Frank Nüesch, Libero Zuppiroli, Detlef Berner, Eduard Tutis, Xiao Wang

In organic light emitting devices, doping of the electroactive organic layer with highly luminescent molecules has been shown to considerably increase device performance and lifetime. In most cases, the doping molecule does not act as a charge donor or an ...

Shadow segmentation and tracking in real-world conditions

Elena Salvador

Visual information, in the form of images and video, comes from the interaction of light with objects. Illumination is a fundamental element of visual information. Detecting and interpreting illumination effects is part of our everyday life visual experien ...

Chromatic contrast detection in spatial chromatic noise

Sabine Süsstrunk, Gianluca Monaci, Gloria Menegaz

The spectral properties of chromatic detection mechanisms were investigated using a noise-masking paradigm. Contrast detection thresholds were measured for a signal with a Gaussian spatial profile, modulated in the equiluminant plane in the presence of spa ...

Space charge and polarization effects upon doping organic light-emitting diodes with pyran-containing donor-acceptor molecules

Frank Nüesch, Libero Zuppiroli, Yiming Cao, Detlef Berner, Xiao Wang

Doping of organic light-emitting devices using highly luminescent molecules is a well-established strategy to improve brightness, efficiency and lifetime or to adjust emission color and color purity. Laser dyes from the pyran-containing donor-acceptor fami ...

Bio-inspired image enhancement for natural color images

Sabine Süsstrunk, Laurence Meylan

Capturing and rendering an image that fulfills the observer's expectations is a difficult task. This is due to the fact that the signal reaching the eye is processed by a complex mechanism before forming a percept, whereas a capturing device only retains t ...

Techniques for Color-Gamut Reduction

Roger Hersch, Sylvain Chosson

Printing with custom inks is of interest both for artistic purposes and for printing security documents such as banknotes. However, in order to create designs with only a few custom inks, a general purpose high-quality gamut reduction technique is needed. ...
