1. An apparatus for performing segmentation-based enhancements of a video image, said apparatus comprising: an input buffer for storing video frames of an incoming video signal; a segmentation controller capable of segmenting a first stored frame into a plurality of segments, each of said plurality of segments comprising a plurality of pixels having at least one common property; an image processor capable of calculating a probability function associated with at least one pixel in said first stored frame, said probability function indicating a probability that said at least one pixel belongs within a first selected one of said plurality of segments; and an enhancement controller capable of enhancing a parameter of said at least one pixel as a function of said probability function of said at least one pixel.
