Colour is an increasingly common feature of computer workstations. New ideas, algorithms and knowledge are needed to harmonize the user's desire for improved aesthetic appeal and the programmer's desire for an interface of greater functionality. This paper discusses several areas in which colour leads to novel functionality, visual search , grouping by colour and colour coding. The current obst...

64 INTERNATIONAL DENTISTRY SA VOL. 12, NO. 2 Although colour as an entity should be regarded as being only one of the many building blocks necessary in the achievement of an aesthetic restorative result, a discordant colour scheme can probably be more devastating to the overall effect than many of the other factors present. It is for this reason that so much time, research and expense has gone ...

Several experiments have been carried out in New Zealand to determine the effects of processing and storage conditions on the colour stability of lamb cuts during retail display. A high proportion of lamb is now being exported in chilled, vacuumpacked form due to the longer storage times attainable under modern processing practices, and the higher prices achieved compared with frozen product. T...

Colour information is not faithfully maintained by a CCTV imaging chain. Since colour can play an important role in identifying objects it is beneficial to be able to account accurately for changes to colour introduced by components in the chain. With this information it will be possible for law enforcement agencies and others to work back along the imaging chain to extract accurate colour info...

It has often been observed that colour is a highly preferred attribute for use in distinguishing descriptions, that is, referring expressions with the purpose of identifying an object within a visual scene. However, most of these observations were based on visual displays containing only colours that were maximally different in hue and for which the language of experimentation possessed basic c...

Many animals display complex colour patterns that comprise several adjacent, often contrasting colour patches. Combining patches of complementary colours increases the overall conspicuousness of the complex pattern, enhancing signal detection. Therefore, selection for conspicuousness may act not only on the design of single colour patches, but also on their combination. Contrasting long- and sh...

An online colour-naming experiment was designed and developed to determine a broad set of colour words in wide cultural use with their corresponding colour ranges in sRGB and Munsell specifications. The quality of the English dataset was analysed in terms of colour centroids, frequency of names, consistency and response time. The importance of basic colour terms was confirmed while it was also ...

Banding can be a major defect in inkjet printing. Knowing the visual sensitivity threshold of inkjet banding is therefore useful for understanding and pushing the technological limit of inkjet printing. There are many reports on the measurement of the human contrast sensitivity using self-luminous sinusoidal contrast targets. There are also reports on measuring the contrast sensitivity of sinus...
