Skin Diseases Detection Models using Image Processing: A Survey

Now a days, skin diseases are mostly found in animals, humans and plants.A skin disease is a particular kind of illness caused by bacteria or an infection.These diseases like alopecia, ringworm, yeast infection, brown spot, allergies, eczema etc. have various dangerous effects on the skin and keep on spreading over time.It becomes important to identify these diseases at their initial stage to control it from spreading.These diseases are identified by using many technologies such as image processing, data mining, artificial neural network (ANN) etc.Recently, image processing has played a major role in this area of research and has widely used for the detection of skin diseases.Techniques like filtering, segmentation, feature extraction, image pre-processing and edge detection etc. are part of image processing and are used to identify the part affected by disease, the form of affected area, its affected area color etc.This paper presents a survey of various skin disease diagnosis systems using image processing techniques in recent times.A comprehensive study of a number of skin disease diagnosis systems are done in this paper, with different methodologies and their performances.
