Abstract
Provided herein is a robust region segmentation method and a system using the same, the method including receiving setting of an image in an input image; calculating representative values for each of an internal portion and an external portion of the region; calculating a cost by substituting the representative values and a pixel value of the image in a cost function, and updating the region based on the calculated cost, wherein the cost function includes a term in which a difference between the updated pixel value and an original pixel value is reflected, thereby enabling an accurate region segmentation even in ambiguous images that are complicated and where division of regions is unclear.
