Abstract

One of the more remarkable properties of the primate visual system is color constancy, the perception of the actual color of a scene independent of the spectral composition of the scene illumination. In this paper we presented one approach to color constancy based on the intensity dependent summation (IDS) filter. IDS is an adaptive filter that displays many of the spatial and frequency domain characteristics of the human visual system including Mach Bands. Our approach utilizes Mach Bands generated by the filter at edges to recover the ratio of reflectances across adjacent boundaries. A diffusion process then generates a multispectral reconstruction of the image.
