Color correction of uncalibrated images for the classification of human skin color

Sabine Süsstrunk, Joanna Marguier

Images of a scene captured with multiple cameras will have different color values due to variations in capture and color rendering across devices. We present a method to accurately retrieve color information from uncalibrated images taken under uncontrolle ...

Dynamic Texture Synthesis: Compact Models Based on Luminance -Chrominance Color Representation

Sabine Süsstrunk, Luciano Sbaiz, Roberto Costantini

Dynamic textures are sequences of images showing temporal regularity. Examples can be found in videos representing smoke, flames, ocean waves, wind-shaken forests, etc. Dynamic texture modelling and synthesis has usually been done considering RGB color ima ...

Exploiting Multi-Temporal Information for SAR Image Segmentation

Jean-Philippe Thiran, Meritxell Bach Cuadra, François Aspert

Earth observation is taking more and more importance in our society. Indeed, recent technologies march allows for satellite images to get ground resolution up to less than one meter. Thus, most of satellite image information obtained begins now to be widel ...

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 ...

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 ...

Incrustation de microstructures par écarts chromatiques

Electronic imaging devices produce the illusion of synthesizing continuous colors by applying halftones, which are repetitive structures of discrete micro-elements. By themselves, these microstructures do not carry any meaning: their only purpose is to foo ...

Cast Shadow Recognition in Color Images

Touradj Ebrahimi, Elena Salvador

Shadows are often integral parts of natural scenes and their identification is an important task in image analysis. In this paper, we propose an algorithm for recognition of shadows cast by objects on the scene's background. The proposed approach is based ...

Color Encodings for Image Databases

Sabine Süsstrunk

There are a number of color encoding standards that have lately been developed ant are being proposed to the imaging community for different encoding steps in the color imaging workflow, optimized for different purposes. In this paper, their applicability ...

Color Strategies for Image Databases

Sabine Süsstrunk

In this paper, color encoding strategies for different image database applications are discussed. The color image workflow is examined in detail, and master and derivative file encoding strategies are outlined in relation to capture, maintenance, and deplo ...

Chromatic adaptation performance of different RGB sensors

Sabine Süsstrunk

Chromatic adaptation transforms are used in imaging system to map image appearance to colorimetry under different illumination sources. In this paper, the performance of different chromatic adaptation transforms (CAT) is compared with the performance of tr ...
