Impairment of colour vision in workers exposed to organic solvents.
OBJECTIVES To investigate loss of colour vision related to exposure to solvents and the role of three enzyme polymorphisms in modifying the risk in exposed workers. METHODS A sample was studied of 68 male dockyard workers and 42 male community controls with and without neuropsychological symptoms from a previous cross sectional study. Indices of cumulative and intensity based exposure to solv...
متن کاملPreliminary Evidence of Superhuman Tetrachromats
The human eye can normally resolve millions of colours, though we use only three colour sensors. This three-dimensional colour vision system is unique to humans and Old-world primates, and is known as trichromacy (3-colour). Elsewhere in the animal kingdom, other types of colour vision abound. Insects exhibit some of the more impressive systems: bees are tetrachromats (4-colour) and can see mor...
متن کاملUnderstanding colour perception and preference
Colour is a critical cue for many vital behavioural tasks: material identifi cation, object recognition and social–sexual signalling. Given the importance of the behavioural uses of colour, and the known perceptual and physiological properties of colour vision, it is likely that preference for coloured objects drives preference for colours themselves. The underlying universality in patterns of ...
متن کاملExtending human-computer interaction by using computer vision and colour recognition
Computer vision techniques supply us with promising human-computer interaction methods by analysing and recognising human movements. The process of detection and tracking human body parts is one of the main steps necessary to reach a robust and precise recognition. Nevertheless, this task is rather difficult, specially when the response from that interaction is required to be in real time. This...
متن کاملEstimation of the Illuminant Colour from Human Skin Colour
Colour is an important and useful feature for object tracking and recognition in computer vision. However, it has the difficulty that the colour of the object changes if the illuminant colour changes. But under known illuminant colour it becomes a robust feature. There are more and more computer vision applications tracking humans, for example in interfaces for human computer interaction or aut...
متن کاملFrom spectral information to animal colour vision: experiments and concepts.
Many animals use the spectral distribution of light to guide behaviour, but whether they have colour vision has been debated for over a century. Our strong subjective experience of colour and the fact that human vision is the paradigm for colour science inevitably raises the question of how we compare with other species. This article outlines four grades of 'colour vision' that can be related t...
