Perceptual Organization in Colour Perception: Inverting the Gamut Expansion Effect [PDF]
I-Perception, 2013 In the well-known gamut expansion effect, uniformly coloured target patches are perceived as more colourful when they are embedded in a uniform grey surround than when they are embedded in a variegated one.

When chemistry is too colourful: gamut clipping in 8-bit sRGB risks misinterpretation of camera-based chemical analysis [PDF]
Digital DiscoveryDigital cameras are increasingly utilised to capture visual changes in chemical processes. Monitoring colour with computer vision tools serves as a valuable proxy for monitoring bulk chemical changes.

All-dielectric Schrödinger colours across the visible spectrum [PDF]
Nature CommunicationsStructural colours, which arise from nanostructures, are pervasive in nature and play a pivotal role in numerous modern applications. Traditional approaches usually deviate from the concept of Schrödinger’s pixels and thus have restricted performance in ...

Selection for gamut mapping colour constancy [PDF]
Image and Vision Computing, 1999 Abstract The requirement that the sensor responses of a camera to a given surface reflectance be constant under changing illumination conditions has led to the development of the so called colour constancy algorithms. Given an image recorded under an unknown illuminant, the task for a colour constancy algorithm is to recover an estimate of the scene ...

Spatial Colour Gamut Mapping by Means of Anisotropic Diffusion [PDF]
Lecture Notes in Computer Science, 2011 We present a computationally efficient, artifact-free, spatial colour gamut mapping algorithm. The proposed algorithm offers a compromise between the colorimetrically optimal gamut clipping and an ideal spatial gamut mapping. It exploits anisotropic diffusion to reduce the introduction of halos often appearing in spatially gamut mapped images.

Ligand-exchange-assisted printing of colloidal nanocrystals to enable all-printed sub-micron optoelectronics [PDF]
Nature CommunicationsAdditive manufacturing enables customised device fabrication for emerging sensing technologies. However, printable (opto)electronic devices with sophisticated architectures, including all-printed photodiodes, face challenges in multi-material and multi ...

A dataset for illuminant- and device- invariant colour barcode decoding with cameras [PDF]
Data in BriefBarcodes are visual representations of data widely used in commerce and administration to compactly codify information about objects, services, and people. Specifically, a barcode is an image composed of parallel lines, with different widths, spacing and

Colour Preferences and Energy Consumption in Retail Lighting Applications [PDF]
E3S Web of Conferences, 2023 Colour preference and energy efficiency have long been considered significant characteristics that cannot be maximized simultaneously. Numerous investigations on colour preference and evaluation have been carried out.

How Visual Discomfort Is Affected by Colour Saturation: A fNIRS Study
IEEE Photonics Journal, 2022 The wide colour gamut displays have improved the viewing experience greatly. However, highly saturated colours may also bring problems such as visual discomfort.
