By imitating the function of receptive fields of the primary visual cortical neurons
we proposed a color-constancy model that combines the ideas of image derivative framework and non-negative sparse coding.From the standpoint of image processing
statistical measures showed that the color compensation ability of the proposed model can be comparable to the current best technical methods.In the view of computational neuroscience
our results also provide support for the notion that primary visual cortex plays critical role on the capacity of color constancy.
