A skillet-based recoloring algorithm for dichromats

The color is a valuable communication resource, not just as part of the message itself, but also as a way of discriminating between the diverse contents of a given message. However, not all people have the ability to distinguish the color in a normal way. About 5% of the world population (8% of men) has a visual impairment, called color vision deficiency (CVD) or, simply, colorblindness. This vision deficiency also has a negative impact in both virtual and real worlds, because it compromises the correct interpretation of the contents across different media and environments. This issue is critical because of the increasing availability of multimedia contents in many places, particularly over the web. This article proposes a novel algorithm to adjust the colors for dichromate people (deuteranopes and protanopes), in particular for still images found over the web via browsers that take advantage of HTML5 markup language for graphics.
