Fractal dimension is used for texture analysis as it correlates to a high degree with the human perception of surface roughness. It has been applied to quantifying the structures of a wide range of objects in biology and medicine. In this paper, we attempt to analyze skin texture images using fractal dimension, and discuss its application to evaluating skin state. This technique could be helpful in extracting human features and could be useful in detecting a wide range of skin diseases. This paper presents a method to calculate the fractal dimension of skin using a camera with lenses of different magnification. We take a series of photographs of the skin using lenses of different magnification as the magnification factor of a fractal set (skin), and count the number of objects (skin cells) in each photograph as the number of self-similar pieces of fractal set.
