Analysis of various techniques of feature extraction on skin lesion images

Skin lesions are any abnormal pattern in the skin of a patient occurring due to some disease, accident etc. Skin lesions images are very important for the doctors to diagnosis disease and treat the patients. Image processing techniques are applied on these images to improve the quality of the image in terms of visibility of the different feature in the image. Enhanced images aid the doctors and healthcare provider to provide better treatment to the patients. Feature extraction of skin lesion images is very significant for classification of skin lesion which helps in identification of skin lesions. Many techniques have been proposed for feature extraction of images. This paper provides a brief overview of the feature extraction techniques used in skin lesion images and observes some areas in which further work can be done.
