Fast Color-Weakness Compensation with Discrimination Threshold Matching

We present a method to compensate color-weak vision along the confusion lines, based on matching between discrimination thresholds of the color-weak observer and of color-normals. The compensation and simulation map preserve color-differences of every pair of colors between color-normals and the color-weak observer. We developed an explicit formula for compensation and simulation of color-weak vision in closed form. The method is easy to implement and fast.
