One embodiment in accordance with the invention relates to detecting a
homogeneous surface. A first surface image is received. A plurality of
values are generated by performing a plurality of auto correlations with
the first surface image and a copy of the first surface image. The
plurality of values includes a first peak value. A determination is made
as to whether a normalized second peak value of the plurality of values
satisfies a defined condition associated with a value. If so, a
homogeneous surface image filter is utilized with a second surface image.
