Colour normalisation to reduce inter-patient and intra-patient variability in microaneurysm detection in colour retinal images [PDF]
, 2005 Images of the human retina vary considerably in their appearance depending on the skin pigmentation (amount of melanin) of the subject. Some form of normalisation of colour in retinal images is required for automated analysis of images if good ...

Gradient‐Structured Polymer Fiber Mats for Broadly Tunable Multicolor and White Lasing
Laser &Photonics Reviews, EarlyView.Hierarchically engineered electrospun fiber mats containing separated red, green, and blue dyes enable highly tunable multicolor and white random lasing. Spatially controlled dye distribution suppresses energy transfer, allowing precise color adjustment across wide color gamuts and accurate reproduction of daylight white standards.

Colorimetry and TV Colour Splitting Systems
Acta Polytechnica, 2001 The colorimetric standard of the present-day television system goes back to the American NTSC system from 1953. In this RGB colorimetric system it is not possible, for basic reasons, to produce a scanning device which will provide signals suitable for ...

Practical considerations for pathologists when selecting digital pathology systems: an ESDIP guide
The Journal of Pathology, EarlyView.Abstract The implementation of digital pathology (DP) has been reported across academic, public, and private laboratory settings, providing valuable insights into workflow transformation. However, comparatively little guidance exists on how DP systems should be evaluated prior to acquisition and deployment.

Optimizing Ball‐Milled Composites for Fast Energy Release Under Shock Compression
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Microparticle additives containing both Al fuel and oxidizer, fabricated by arrested reactive milling (ARM), could potentially increase the power of energetic materials such as HMX because they contain premixed fuel and oxidizer. Optimizing shock reactivity requires exploring a vast parametric space encompassing composition, milling parameters

Gamut Volume Index: a color preference metric based on meta-analysis and optimized colour samples
, 2017 A novel metric named Gamut Volume Index (GVI) is proposed for evaluating the colour preference of lighting. This metric is based on the absolute gamut volume of optimized colour samples.
