Abstract
A method, system and computer program for segmenting an image are provided. The system may include an image acquisition system for acquiring a plurality of images; and a processor for clustering pixels from one of the images into one or more segments, each segment being defined in a state of either stable, mesostable or unstable, the processor further performing the clustering by determining residual pixels changing by more than a predetermined threshold, grouping the determined residual pixels to form segments selected from the group of unstable and mesostable segments, determining depth for all unstable and mesostable segments, transitioning unstable segments to corresponding mesostable segments if the unstable segment is determined to have a valid depth, transitioning mesostable segments to corresponding stable segments upon a determination that one or more predetermined stability criteria have been met, and merging one or more stable and mesostable segments.
