3D In-Vivo Measurement of Skin Topography Using Photometric Stereo
Ali Sohaib, Abdul Rehman Farooq, Lyndon Neal Smith, Melvyn Lionel Smith · 2012
Increased demand for treatment of skin wrinkles has led to a proliferation of different pharmaceutical and surgical treatment methods.However there still remains a lack of quantitative, objective, easily utilizable and reproducible wrinkle classification system by which these treatments can be studied and compared.We propose the use of a novel photometric stereo based technique as a potentially efficient and economical way for quantitative evaluation of skin topography.Also presented is an algorithm for improving depth estimates of skin using photometric stereo and Fractals based technique for quantification of skin topography which unlike existing 2D roughness parameters makes use of complete 3D topographical information.
