Empirically detecting colour: can we use solar cells as colour sensors?
… the possibility of using solar cells as a colour sensor. Colour sensors already exist, yet they are either costly or fail at correctly sensing monochromatic light. Our experiment was set up in order to see if a solar cell would create a unique current response to a specific monochromatic …

Structural Colour in Fruits
Structural colour arises from the constructive interference of light with a material structured on a lengthscale corresponding to optical wavelengths. This phenomenon is responsible for the appearance of many of the brightest colours in nature and recently the existence of structural colouration in …

The Colour concept generator: a computer tool to propose colour concepts for products.
… the design and evaluation of a computer tool (Colour Concept Generator) to produce colour schemes for products from verbal descriptors depicting a required aesthetic image or style. The system was designed to translate between descriptive words and colour combinations and aims to provide a form …

Early detection of oesophageal cancer based on colour appearance and colour-based data augmentation
… This research investigates the contribution of colour attribute in diagnosis of OC. Two studies are conducted. One is to distinguish colour differences between images of low grade, high grade of OC and cancer as well as normal skin colours. The second part of study focuses on the colour-based …

Colour differentiation in digitial images
… of green vegetables in digital images, the colour appearance of the vegetable is one of the main factors. In general, green colour represents good quality and yellow colour represents poor quality empirically for green-vegetable. The colour appearance is mainly determined by its hue, …

The colour of AuAgCu alloys
… The use of an ellipsometer to derive the colour co-ordinates of a sample is a novel technique. The ellipsometer has the advantages for use as a physical colorimeter in that its calibration is gonio-metric and it does not require a particularly stable light source or secondary reflectance …

Colour out of space: colour in the construction and usage of monuments of Neolithic Atlantic Europe.
Colour is a fundamental human experience – if not a universally constant one. There are, after all, individuals who are colour-blind to various degrees, or even those that see extra colours. However, there is something about the perception and categorisation of colour that is near uniform across …

The time-course of colour vision
… each investigating temporal properties of colour vision processing in human observers. The first experiment replicates and extends an experiment by Stromeyer et al. (1991). We look for a phase difference between combined temporal modulations in orthogonal directions in colour space, which …

Computer-assisted colour fundus image analysis
Research in automatic retina image analysis has become increasingly important in ophthalmology. The retina is the only location where blood vessels can be directly visualized non-invasively in vivo. Hence, it serves as a ‘window’ to some of the pathologies like glaucoma, cerebrovascular and …
