Abstract
A nonlinear picture-to-picture transformation is introduced and compared with a straightforward linear transformation. The criterion for comparison is based on the desire to smooth noisy or textured regions while retaining edge definition. Selected examples from a large number of simulations are presented. The transformation presented is believed to be superior to many techniques presently being employed.
