An edge refinement system includes a computer-readable medium encoded with a computer program having computer readable code for identifying carrier cells among shadow cells and highlight cells of a segmented image, computer readable code for determining if a predetermined edge condition is met by each of the identified carrier cells, and computer readable code for re-classifying the carrier cell as a non-carrier cell when the predetermined edge condition is met. The edge refinement system further includes memory and a processor operatively coupled to the memory and to the computer-readable medium.
