1. A method of segmenting an arbitrary first image feature in a video image frame from an adjacent second image feature in the image video frame, the arbitrary first image feature having an interior that is bounded by a perimeter and has a first image characteristic and the second image feature having a second image characteristic different from the first image characteristic, comprising: obtaining within the interior an interior outline of the perimeter of the arbitrary first image feature, the interior outline being generally within a predetermined distance of the perimeter; and expanding the interior outline of the perimeter according to a predetermined factor to form a conformed outline representing the perimeter of the arbitrary first image feature; wherein the predetermined factor includes relative multi-dimensional proximity to the first and second image characteristics of selected pixels adjacent the outline.
