Segmenting memory colours

Memory colours refer to the colour of specific image classes that have the essential attribute of being perceived in a consistent manner by human observers. In colour correction or rendering tasks, this consistency implies that they have to be faithfully r ...

Colouring the near infrared

Sabine Süsstrunk

Current digital camera sensors are inherently sensitive to the near-infrared part of the spectrum. To prevent the near-IR contamination of images, an IR blocking filter (hot mirror) is placed in front of the sensor. In this work, we start by replacing the ...

Color Match: An Imaging Based Mobile Cosmetics Advisory Service

Sabine Süsstrunk

In this paper we describe an exploratory study of a mobile cosmetic advisory system that enables women to select appropriate colors of cosmetics. This system is intended for commercial use to address the problem of foundation color selection. Although wome ...

Salient Region Detection and Segmentation

Sabine Süsstrunk, Radhakrishna Achanta, Patricia Wils, Francisco Estrada

Detection of salient image regions is useful for applications like image segmentation, adaptive compression, and region-based image retrieval. In this paper we present a novel method to determine salient regions in images using low-level features of lumina ...

Illuminant retrieval for fixed location cameras

Joanna Marguier, Sabine Süsstrunk

Fixed location cameras, such as panoramic cameras or surveillance cameras, are very common. In images taken with these cameras, there will be changes in lighting and dynamic image content, but there will also be constant objects in the background. We propo ...

The Flux: Creating a Large Annotated Image Database

Daniel Tamburrino, Sabine Süsstrunk, Patrick Vandewalle, Patrick Merryl Marlon Schönmann

From image retrieval to image classification, all research shares one common requirement: a good image database to test or train the algorithms. In order to create a large database of images, we set up a project that allowed gathering a collection of more ...

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 ...

Higher Order SVD Analysis for Dynamic Texture Synthesis

Luciano Sbaiz, Sabine Süsstrunk, Roberto Costantini

Videos representing flames, water, smoke, etc. are often defined as dynamic textures: "textures" because they are characterized by redundant repetition of a pattern and "dynamic" because this repetition is also in time and not only in space. Dynamic textur ...

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

Laurence Meylan, Sabine Süsstrunk

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 ...

Tone Mapping For High Dynamic Range Displays

Laurence Meylan, Sabine Süsstrunk

We address the problem of re-rendering images to high dynamic range (HDR) displays, which were originally tone-mapped to standard displays. As these new HDR displays have a much larger dynamic range than standard displays, an image rendered to standard mon ...

Assessing human skin color from uncalibrated images

Joanna Marguier, Sabine Süsstrunk

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

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

Joanna Marguier, Sabine Süsstrunk

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 ...

Multidimensional image enhancement from a set of unregistered differently exposed images

Laurence Meylan, Sabine Süsstrunk, Patrick Vandewalle, Ali Ajdari Rad

If multiple images of a scene are available instead of a single image, we can use the additional information conveyed by the set of images to generate a higher quality image. This can be done along multiple dimensions. Super-resolution algorithms use a set ...

Joint Demosaicing and Super-Resolution Imaging from a Set of Unregistered Aliased Images

Sabine Süsstrunk, Patrick Vandewalle, Karim Krichane

We present a new algorithm that performs demosaicing and super-resolution jointly from a set of raw images sampled with a color filter array. Such a combined approach allows us to compute the alignment parameters between the images on the raw camera data b ...

Effects of Motion and Configural Complexity on Color Transparency Perception

Sabine Süsstrunk, Peggy Gerardin

We tested whether motion and configural complexity affect perceived transparency. A series of five coherent chromatic transformations in color space was applied across a figure: translation, convergence, shear, divergence and rotation. The stimuli consiste ...

The Reproduction of Specular Highlights on High Dynamic Range Displays

Laurence Meylan, Sabine Süsstrunk

Recent advances in the design of high dynamic range (HDR) monitors enable the display of images having a large dynamic range, close to that encountered in the real world. As their usage will increase, we will be confronted with the problem of rerendering i ...

Registration of Aliased Images for Super-Resolution Imaging

Martin Vetterli, Luciano Sbaiz, Sabine Süsstrunk, Patrick Vandewalle

Super-resolution imaging techniques reconstruct a high resolution image from a set of low resolution images that are taken from almost the same point of view. The problem can be subdivided into two main parts: an image registration part where the different ...

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

Luciano Sbaiz, Sabine Süsstrunk, 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 ...

A Frequency Domain Approach to Registration of Aliased Images with Application to Super-Resolution

Martin Vetterli, Sabine Süsstrunk, Patrick Vandewalle

Super-resolution algorithms reconstruct a high resolution image from a set of low resolution images of a scene. Precise alignment of the input images is an essential part of such algorithms. If the low resolution images are undersampled and have aliasing a ...

HDR CFA Image Rendering

Laurence Meylan, Sabine Süsstrunk

We propose a method for high dynamic range (HDR) mapping that is directly applied on the color filter array (CFA) image instead of the already demosaiced image. This rendering is closer to retinal processing where an image is acquired by a mosaic of cones ...
