Multi-Layer Background Subtraction Based on Color and Texture

Jean-Marc Odobez

In this paper, we propose a robust multi-layer background subtraction technique which takes advantages of local texture features represented by local binary patterns (LBP) and photometric invariant color measurements in RGB color space. LBP can work robust ...

Complex Ambiguity-Free Fourier Domain Optical Coherence Tomography through Transverse Scanning

Theo Lasser, Rainer Leitgeb, Roland Michaely

We introduce a simple and cheap method for phase-shifting Fourier domain optical coherence tomography (FDOCT) that does not need additional devices and can easily be implemented. A small beam offset at the fast beam-scanning mirror introduces a causal phas ...

Automatic Red-Eye Removal based on Sclera and Skin Tone Detection

Patrick Vandewalle, Flavien Volken, Johann Terrier

It is well-known that taking portrait photographs with a built in camera may create a red-eye effect. This effect is caused by the light entering the subject’s eye through the pupil and reflecting from the retina back to the sensor. These red eyes are prob ...

Consistent image-based measurement and classification of skin color

Sabine Süsstrunk

Little prior image processing work has addressed estimation and classification of skin color in a manner that is independent of camera and illuminant. To this end, we first present new methods for 1) fast, easy-to-use image color correction, with specializ ...

Computing Chromatic Adaptation

Most of today’s chromatic adaptation transforms (CATs) are based on a modified form of the von Kries chromatic adaptation model, which states that chromatic adaptation is an independent gain regulation of the three photoreceptors in the human visual system ...

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 ...

Influence of Spectral Sensitivity Functions on color demosaicing

Sabine Süsstrunk, Joanna Marguier

Color images acquired through single chip digital cameras using a color filter array (CFA) contain a mixture of luminance and opponent chromatic information that share their representation in the spatial Fourier spectrum. This mixture could result in alias ...

Method for hair removal

Hubert van den Bergh, Georges Wagnières

A method for hair removal from a skin area by selective photo-inactivation of the pilo-sebaceous apparatus using ALA, derivatives of ALA, for example those with alkylene-glycol chains. Selectivity of the method is further enhanced by treatment of the epide ...

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 ...
