Abstract
A segmentation method segments selected objects from other objects within a video image frame. The objects may be of arbitrary configuration and preferably represent distinct image features in a display image. An interior outline is formed within the interior of the object perimeter. The interior outline is expanded automatically to form an exterior outline. Pixels between the interior outline and the exterior outline are classified according to predefined attributes as to whether they are within object interior, thereby to identify automatically a conformed outline that is fitted to the object perimeter.
