Abstract

Malignant Melanoma (MM) is the third most frequently occurring human skin cancer. It is the deadliest form of all skin cancers and arises from cancerous growth in pigmented skin lesion. Research in the field melanoma is very important because it has a good chance to be cure if treated in the early stages. Nowadays melanoma computer-aided diagnosis research is very popular with based on computer algorithms. A software solution designed to analyze photographs of the lesions where the dermatologists will capture the image of a melanoma using a digital dermathoscopy will process the image and provide an output diagnosis in an automated manner. ABCD (A: asymmetry, B: border, C: colour, D: differential structures) score calculation, lesion image need some preprocessing. Because of the lesion image as like thick hair, illumination, thin blood vessels, skin lines were affecting computer based algorithm. In this study, we have proposed a new method for pre-processing to remove hairs and illumination effects from dermathoscopic image to calculate the ABCD score successfully by software. We compare the performance of a classical method to find the border of the lesion by using before and after filtering. Our experimental results indicate that proposed method can eliminate the effect of hairs and illumination
