1. A method for analysis of variables operable to transform an input variable into an output variable comprising the following steps: (a) applying a Threshold Filter to a difference of a Displacement Variable and an input variable producing a first scalar field of said Displacement Variable; and (b) filtering said first scalar field of step (a) with a first Averaging Filter operable to perform a function selected from the group consisting of time averaging function, spatial averaging function, and time and spatial averaging function to produce a second scalar field of said Displacement Variable.
