Abstract |
The goal of this project is to measure the fractal dimension of 3D images of the human skin (on the corner of the eye). This gives a roughness measure of the skin. It allows then to see the evolution of the roughness over a period of time, to evaluate the effect of a moistening cream. The fractal dimension is estimated by calculating the 2D variogram of the image. The dimension is proportional to the slope of the variogram in a log-log graph. It can be evaluated with respect to the orientation. Measures show that the fractal dimension depends on the direction, and that the fractal dimension of skin under a moistening cream treatment tends to reduce over time. Moreover, significant difference of the fractal dimension is measured between young and old skin. .
