Permuting pixel locations preserves the multiset of luminance values, hence its histogram and every sum ∑i​f(Ii​), including raw moments. It need not preserve spatial correlations, edges or relations between highlights and shading. This proves nonuniqueness of an image from its histogram; a particular perceptual consequence requires experiment.
