Semantic Awareness for Automatic Image Interpretation

Albrecht Johannes Lindner

Finding relations between image semantics and image characteristics is a problem of long standing in computer vision and related fields. Despite persistent efforts and significant advances in the field, today’s computers are still strikingly unable to achi ...

Near-Infrared Guided Color Image Dehazing

Sabine Süsstrunk, Chen Feng

Near-infrared (NIR) light has stronger penetration capability than visible light due to its long wavelength, thus being less scattered by particles in the air. This makes it desirable for image dehazing to unveil details of distant objects in landscape pho ...

Visualization of data concerns most scientists. The use of color is required in order to display multidimensional information. In addition, color encoding a univariate image can improve the interpretation significantly. However up to 10% of the adult male ...

The temporal dynamics of feature integration for color and form

Michael Herzog

When two visual stimuli are presented in rapid succession only one fused image is perceived. For example, a red disk followed by a green disk is perceived as a single yellow disk (e.g., Efron, Perc Psychophys, 1973). For two verniers that last 30ms each, i ...

Luminance contours can gate afterimage colors and "real" colors

Marcus Leonardus Vergeer

It has long been known that colored images may elicit afterimages in complementary colors. We have already shown (Van Lier, Vergeer, & Anstis, 2009) that one and the same adapting image may result in different afterimage colors, depending on the test conto ...

A colorimetric CO sensor for fire detection

Nico de Rooij, Danick Briand, Kay Severin, Jérôme Courbat, Mirela Pascu

We report on a colorimetric carbon monoxide (CO) sensor based on a rhodium complex. The sensor relies on changes in the light absorption properties of the chemochromic reagent when exposed to the gas. Its optical properties in solution and in a polymeric m ...

Constrained Acquisition of Ink Spreading Curves From Printed Color Images

Roger Hersch, Thomas Bugnon

Today's spectral reflection prediction models are able to predict the reflection spectra of printed color images with an accuracy as high as the reproduction variability allows. However, to calibrate such models, special uniform calibration patches need to ...

A subjective study of the influence of color information on visual quality assessment of high resolution pictures

Touradj Ebrahimi, Francesca De Simone, Frédéric Dufaux

This paper presents the design and the results of a psychovisual experiment which aims at understanding how the color information affects the perceived quality of a high resolution still picture. The results of this experiment help to shed light into the i ...

A Home Décor expert in your camera

Sabine Süsstrunk, Joanna Marguier

We present a method to give color advice for Home Décor using images of room finishes, such as paint, flooring, or textiles, taken with uncalibrated cameras. Due to variations in color rendering across devices, an object imaged with different cameras will ...

Filling-in afterimage colors between the lines

Marcus Leonardus Vergeer

It is known that when a colored surface is viewed for some time and a blank screen is presented afterwards, an afterimage can be perceived in the complementary color. Color appearances in afterimages are due to adaptation of retinal cones and they are espe ...
