  • The border detection error was quantified using a metric based on dermatologist-annotated ground truth.
  • The proposed method's performance was compared against three other automated methods and a second dermatologist's manual annotations.
  • The results indicate the effectiveness of the developed algorithm.

Conclusions:

  • The presented method achieves both fast and accurate border detection in dermoscopy images.
  • This contributes to improving the reliability of computer-aided skin cancer diagnosis.
