The ability to differentiate between colours varies from individual to individual. This variation is attributed to factors such as the presence of colour blindness. Colour is used to encode information in information visualizations. An example of such an encoding is categorization using colour (e.g., green for land, blue for water). As a result of the variation in colour differentiation ability...

A search is performed in symmetric 3-jet hadronic Z decay events for evidence of colour singlet exchange and for colour reconnection effects predicted by the Rathsman model. Asymmetries in particle flow and the angular separation of particles are found to be sensitive to such effects. 95% upper limits of 7-9% are found for the fraction of colour singlet exchange, and of 0.93% for the colour rec...

The problems inherent in providing natural language generation of colour names are discussed. Three models for generating natural language descriptions of HSL colours are described. The effectiveness of these models in describing colours is compared experimentally. It is concluded that a rigid syntactic mapping of HSL components to orthogonal linguistic axes is generally inferior to exhaustive ...

We provide novel evidence for a two-stage model of visual search applied to the selection based on top-down cues to stimulus colour and orientation. The model supposes that visual displays are first parsed into colour based groups, a process that is modulated by the presence of an initial cue to the target's colour. Subsequently search is directed to other featural properties represented within...

Asplünd’s metric, which is useful for pattern matching, consists in a double-sided probing, i.e. the over-graph and the sub-graph of a function are probed jointly. This paper extends the Asplünd’s metric we previously defined for colour and multivariate images using a marginal approach (i.e. component by component) to the first spatiocolour Asplünd’s metric based on the vectorial colour LIP mod...

a participatory rural appraisal technique (prat) was used to obtain information from 132 randomly selected turkey farmers in two out of four agricultural development zones in kwara state, nigeria. data were obtained on socio-occupational status of farmers, their production objectives, experience, flock structure, management practices, marketing and consumption of turkey eggs. the results showed...
