An Evaluation Framework for Spectral Filter Array Cameras to Optimize Skin Diagnosis
Sensors, 2019 Comparing and selecting an adequate spectral filter array (SFA) camera is application-specific and usually requires extensive prior measurements. An evaluation framework for SFA cameras is proposed and three cameras are tested in the context of skin ...

Teaching and Professional Fellowship Report 2002/3: Colour and Computing [PDF]
, 2003 An exploration of new teaching and learning methodologies relating material colour use to digital colour and the computer's speed, control, 'sensitivity' and new possibilities to develop colour ideas of practical use in the ...

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Calibration and removal of lateral chromatic aberration in images [PDF]
, 2007 This paper addresses the problem of compensating for lateral chromatic aberration in digital images through colour plane realignment. Two main contributions are made: the derivation of a model for lateral chromatic aberration in images, and the ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin
FEBS Letters, EarlyView.The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Optimisation of Convolution-Based Image Lightness Processing
Journal of ImagingIn the convolutional retinex approach to image lightness processing, an image is filtered by a centre/surround operator that is designed to mitigate the effects of shading (illumination gradients), which in turn compresses the dynamic range.

The 4th Dimension. Wittgenstein on Colour and Imagination [PDF]
, 2002 In this paper I first discuss the colour-octahedron and the position of this model as an idealized system with respect to the remarks on colour-concepts in Remarks on Colour (RC).

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
