Probability Transforms of Digital Pictures
Abstract
Let g be any local property (e.g., gray level or gradient magnitude) defined on a digital picture. Let pg(z) be the relative frequency with which g has value z. At each point (x,y) of the picture we can display pg(g(x,y)), appropriately scaled; the result is called the pg-transform of the picture. Alternatively, we can use joint or conditional frequencies of pairs of local properties to define transforms. This note gives examples of such transforms for various g's and h's and discusses their possible uses and limitations.
