ANALYSIS OF LMS DALTONIZATION ALGORITHM FOR ADJUSTING IMAGE COLOR FOR DEUTERANOPIA

Abstract

Color Blindness is a vision deficiency that leads to missing out of some colors present in an
image or video. This in turn affects the lives (both personal and professional) of people
suffering from it. In order to limit or solve color blindness problems, digital image
processing algorithms for adjusting image color have been proposed in the literature.
Amongst the most prevalent, RGB color contrasting and LAB color correction algorithms
are said to have no clear theoretical grounds. Both algorithms are based upon experimental
procedures, mostly on trial and error in the presence of color blind subjects. LMS
Daltonization is another type of algorithm that has little disadvantage on the adjusted
images, as close scrutiny is required to observe any differences. In this work, LMS
Daltonization method was analysed for Deuteranopia type of color blindness. All
simulations were done in Matlab. Results of adjusted image color obtained proved that LMS
daltonization is a good algorithm for adjusting colors in images for deuteranopia color
blindness, as it has satisfied its quality as mentioned above
