Thee Role of Image Processing in Dermatologia
Dermatologs have long depended on dermoskopy and naked-eye examination to identify signious lesions. However, even experivenced clinicians can face variability in interpretation, especially when difinishing between benign and cantorant lesions. Image processing offers a systematic approach to enhance image quality, istate regions of interest, and extract quantitative contaures that support diagnostic decions.

Core Image Processing Techniques

Raw dermoscopic images of ten suffer from artifacts such as hair, bubbles, uneven illumination, and color variations. Preprocessing techniques are applied tich normalize these images and improwize empient analyses. Common methods included color constancy algorythms (np., Gray Worlds, Shades of Gray), contrast enhancement using histogram equalistion or adaptativa techniques, and hair remoival via morphological filters or inpainpaing.

Lesion Segmentation
Segmention refers to thee process of isolating thee skin lesion from thee arounding healthy tissue. Accurate segmentation is critial because it defenes the region from which quarteres are extractted.
