Designing color filter arrays for the joint capture of visible and near-infrared images

Martin Vetterli, Sabine Süsstrunk, Yue Lu

Digital camera sensors are inherently sensitive to the near-infrared (NIR) part of the light spectrum. In this paper, we propose a general design for color filter arrays that allow the joint capture of visible/NIR images using a single sensor. We pose the ...

Using Digital Cameras as Quasi-Spectral Radiometers to Study Complex Fenestration Systems

Marilyne Andersen

This work discusses the use of digital cameras fitted with absorption filters as quasi-spectral radiometers. By filtering incident light into selected wavelength intervals, accurate estimates of radiances can be made for unknown spectra. This approach is b ...

True color communication

Sabine Süsstrunk

Embodiments of the present invention recite a system and method for conveying the true color of a subject. In one embodiment, the present invention comprises an image capture device, an imaged reference color set comprising at least one reference color, an ...

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 ...

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

Sabine Süsstrunk, Laurence Meylan

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 ...

HDR CFA Image Rendering

Sabine Süsstrunk, Laurence Meylan

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 ...

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 ...

Spatio-chromatic PCA of a mosaiced color image

Sabine Süsstrunk

In this paper, we analyze whether Principal Component Analysis (PCA) is an appropriate tool for estimating spatial information in spatio- chromatic mosaiced images. Ruderman et al. 1 have shown that the spatio- chromatic principal components of cone images ...

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 ...

Accurate Color Demosaicing inspired by the Human Visual System

Sabine Süsstrunk

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