The effects of intensity variations of the global illumination are discussed and constraints deduced that restrict the shape of a function that maps the histogram of a template to the histogram of an image location. This approach is illustrated for simple pattern matching and for a combination with a PCA (\emph{Eigenface}) model of the grey-level appearance.
