1. A method for quantizing spatial coherency of at least one dominant color of an image region, comprising:
normalizing a weighted sum of per-dominant color-spatial coherencies; and
non-uniformly quantizing the normalized spatial coherency to a predetermined range, wherein the normalized values of spatial
coherency less than a first predetermined value are set to a quantized value of a first predetermined range, and wherein the
normalized values of spatial coherency in connection with a second predetermined value are uniformly quantized to a quantized
second predetermined range.
