A study on the simulation methods to model the elderly color perception

Medical reports show that as humans age, they experience color perception loss. It is caused by the yellowing occurring on the human lens and the reduction of the human pupil size. These occurrences change the spectral characteristics and reduce the amount of light at the retina. Thus, the images perceived become darker and yellowish as we grow older. Due to this, it may affect the accuracy of the information obtained from color images on websites and smartphone applications. To understand the difficulties experienced by the elderly, researchers have proposed methods to model their color perception. In this paper, we conduct a study on three existing methods that simulate elderly color perception. The study aims to understand their theoretical foundations and mathematical formulation. Also, we study the age-related change to the chromaticity and colors of the simulated images from these methods. Moreover, we also compute the color difference between the original and simulated images.
