The correction of the effects of color-weakness is difficultif not impossible. One of the reasons is that are no objectivecriterions available to evaluate corrections since it is difficult toquantify the color perception of an individual. Also the degreeand the character of color-weakness vary widely among individualsand different color stimuli. In this paper, we use Riemanngeometry to construct a new method for color-weakness correction.The basic mechanism is the matching between the discriminationthresholds of color-weak and of color-normal observers.The goal is to provide the same color perception of color-normalobservers to the color-weak observer: it takes into account theindividual differences between observers and since it defines aglobal deformation of the whole color space it is applicable forcorrection of complex visual inputs such as natural images.
