Patent ID: 8634110

Claim:
An edge refinement system, comprising a non-transitory 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, the computer readable code for determining including: computer readable code for performing a range test, the computer readable code for performing the range test including computer readable code for determining if a range between a lightest pixel value and a darkest pixel value in a respective one of the identified carrier cells exceeds a given threshold; and computer readable code for performing a solid test on the respective one of the identified carrier cells having been subjected to the range test and remaining a carrier cell based on the range test, the computer readable code for performing the solid test including computer readable code for recognizing the predetermined edge condition when a preset minimum number of pixels in the respective one of the identified carrier cells have a same value; and computer readable code for re-classifying the carrier cell as a non-carrier cell when the predetermined edge condition is met; wherein the system further includes memory and a processor operatively coupled to the memory and to the non-transitory computer-readable medium.
