Abstract:
Dermoscopy technique is widely used for image acquisition in diagnosis of skin cancer. Artefacts such as air bubbles, ruler markings and hair which are covering skin affect the segmentation process. To improve the accuracy of segmentation, it is necessary to remove these artefacts. Also, it is possible that low contrast of dermoscopic image can give poor results of segmentation. So contrast of dermoscopic image has to be increased. This paper shows results of artefact removal and contrast enhancement for dermoscopic images using different image processing techniques.
