Color vision deficiencies (CVD) affect the everyday lives of a large number of people, but it is difficult for others – even friends and family members – to understand the experience of having CVD. Simulation tools can help provide this experience; however, current simulations are based on general models that have several limitations, and therefore cannot accurately reflect the perceptual capab...

Stomatopods (mantis shrimps) possess one of the most complex visual systems in the animal kingdom. Each eye is capable of monocular distance judgement, colour vision involving eight or more primary channels and polarisation vision. This involves a series of eye movements unique among the crustaceans. Furthermore, each eye usually acts almost entirely independently of the other. Colour, in parti...

Digital cameras with color image sensors are now commonplace. The same is true for the computing power and device interfaces necessary to handle the additional data from color images. What’s more, as users become familiar and comfortable with machine vision technology, they seek to tackle more difficult or previously unsolvable applications. These circumstances combine to make color machine vis...

This paper confer the reasons for color vision defects in human eye. This paper also discuss the design and development system for the people who are having problem in their visual system, such as color blindness, low vision, or visual field defects. A new model has been proposed that examine the color vision, vision field defects and visual acuity. Model has proposed that is working on the per...

color blindness is a common x-linked genetic disorder. however, most of color blinds remain undetected due to absence of proper screening. our study was to determine the prevalence of red-green color vision defects among manipuri muslim males and females. the study could help in decreasing birth of children with this disorder as muslims commonly perform consanguineous marriage among themselves....

This paper argues for the reality of qualia as aspects of phenomenal experience. The argument focuses on color vision and develops a dispositionalist, subjectivist account of what it is for an object to be colored. I consider objections to dispositionalism on epistemological, metaphysical, and ‘ordinary’ grounds. I distinguish my representative realism from sense-data theories and from recent ‘...

In many tasks of machine vision applications, it is important that recorded colors remain constant, in the real world scene, even under changes of the illuminants and the cameras. Contrary to the human vision system, a machine vision system exhibits inadequate adaptability to the variation of lighting conditions. Automatic white balance control available in commercial cameras is not sufficient ...

The optical instruments design for binocular vision has become an earnest demand towards the arrival of an ageing society. It is necessary to measure how color difference between left and right images by elderly people, which the color rivalry occurs. In this study, we measured the limit of binocular color fusion in the normal vision and the cataract experiencing vision which is aiming to simul...

Previous research has shown that it is possible to isolate a response to pattern from the visual evoked cortical potential. This study investigated the optimum conditions for yielding a pattern response and then applied the pattern response to a test of color vision. The results showed that individuals with normal color vision will give a response to pattern when the pattern is formed of either...

How does the visual cortex encode color? I summarize a theory in which cortical double-opponent color neurons perform a role in color constancy and a complementary set of color-luminance neurons function to selectively correct for color fringes induced by chromatic aberration in the eye. The theory may help to resolve an ongoing debate concerning the functional properties of cortical receptive ...
