Saliency based color accessibility
0 likes166 views
The document discusses a method for quantifying information loss and gain related to individual differences in color perception, particularly for color-deficient observers, based on visual salience. It presents a proposed system that predicts reduced image preference in color-deficient individuals and suggests saliency-guided manipulations can enhance visual accessibility. The document also outlines the hardware and software requirements for the system's implementation.

However, it has been difficult to quantify the individual cognitive variation in colored scene and to predict its complex impacts on the behaviors. We developed a method for quantifying and visualizing information loss and gain resulting from individual differences in spectral sensitivity based on visual salience. We first modeled the visual salience for color-deficient observers, and found that the predicted losses and gains in local image salience derived from normal and color-blind models were correlated with the subjective judgment of image saliency in psychophysical experiments, i.e., saliency loss predicted reduced image preference in color- deficient observers. Moreover, saliency-guided image manipulations sufficiently compensated for individual differences in saliency. This visual saliency approach allows for quantification of information extracted from complex visual scenes and can be used as an image compensation to enhance visual accessibility by color- deficient individuals.

EXISTING SYSTEM In existing system perception of color varies markedly between individuals because of differential expression of photo pigments in retinal cones. DRAWBACK OF EXISTING SYSTEM It has been difficult to quantify the individual cognitive variation in colored scene and to predict its complex impacts on the behaviors. It lacking one class of photo pigments are deficient in their ability to discriminate colors
