C# Class Accord.Imaging.Filters.GrayWorld

Gray World filter for color normalization.

The grey world normalization makes the assumption that changes in the lighting spectrum can be modeled by three constant factors applied to the red, green and blue channels of color[2]. More specifically, a change in illuminated color can be modeled as a scaling α, β and γ in the R, G and B color channels and as such the grey world algorithm is invariant to illumination color variations.
