DISCRIMINATION OF BASAL CELL CARCINOMA FROM BENIGN LESIONS BASED ON EXTRACTION OF ULCER FEATURES IN POLARIZED-LIGHT DERMOSCOPY IMAGES

摘要

BackgroundUlcers are frequently visible in magnified, cross-polarized, dermoscopy images of basal cell carcinoma. An ulcer without a history of trauma, a so-called “atraumatic” ulcer, is an important sign of basal cell carcinoma, the most common skin cancer. Distinguishing such ulcers from similar features found in benign lesions is challenging. In this research, color and texture features of ulcers are analyzed to discriminate basal cell carcinoma from benign lesions.
