High-resolution Imaging System for Omnidirectional Illuminant Estimation

The present paper realizes multiband spectral imaging with high spatial resolution for omnidirectional estimation of scene illuminant in a simple measuring system. To overcome the mirrored ball problems, we propose a multiband omnidirectional imaging system using a high-resolution trichromatic digital camera, a fisheye lens, and two color filters of commercial use. The spatial resolution of omn...

Chromatic Adaptation and Illuminant Estimation

Chromatic Adaptation is the ability of the human visual system to approximately preserve the appearance of an object color, no matter which light “color” illuminates a particular scene. We perceive a white piece of paper as white, regardless whether viewed under a bluish daylight or yellowish tungsten light source. Similar effects can be observed with other color hues. Figure 1 illustrates this...

Illuminant estimation as cue combination.

This work briefly describes a model for illuminant estimation based on combination of candidate illuminant cues. Many of the research issues concerning cue combination in depth and shape perception translate well to the study of surface color perception. I describe and illustrate a particular experimental approach (perturbation analysis) employed in the study of depth and shape that is useful i...

Illuminant Estimation: Beyond the Bases

We describe spectral estimation principles that are useful for color balancing, color conversion, and sensor design. The principles extend conventional estimation methods, which rely on linear models of the input data, by characterizing the distribution or structure of the linear model coefficients. When the linear model coefficients of the input data are highly structured, it is possible to im...

Reflectance reconstruction for multispectral imaging by adaptive Wiener estimation.

In multispectral imaging, Wiener estimation is widely adopted for the reconstruction of spectral reflectance. We propose an improved reflectance reconstruction method by adaptively selecting training samples for the autocorrelation matrix calculation in Wiener estimation, without a prior knowledge of the spectral information of the samples being imaged. The performance of the proposed adaptive ...
