Comparative study of different methodologies to detect Melanoma

Skin cancer is increasing worldwide due to ultraviolet rays radiation. Predominantly affecting only fair skinned people, recent cases suggest that it is affecting even darker skinned people. Melanoma is a form of skin cancer which may prove to be fatal if allowed to go undetected for long periods of time. It even poses the threat of spreading to other organs in the body. Melanoma starts off as a harmless looking mole on the skin and thus early-detection of the same by untrained people is difficult. Over the last few decades, the number of cases of Melanoma has been increasing. Having realized these factors, many computer-aided techniques have been designed to enable quick and easy detection of the same. This paper analyzes the various techniques employed for the detection of Melanoma.
