Dichromacy is a medical condition in which a person is unable to distinguish all colors of the spectrum accurately due to the absence of one cone type within the retina of the eye. No known cure exists for dichromacy so techniques have been created to help improve color perception among affected individuals. This paper investigates a novel perceptually-adaptive technique for enhancing details within still images for persons suffering from dichromacy. A non-linear hue remapping is adaptively applied to the still images to improve color differentiation while preserving the aesthetics of the images. Simulations show that the enhanced images preserve visual detail and maintain the aesthetics of the original image.
