OLE: FACIAL IMAGING SYSTEM WITH OVERHEAD LIGHTING ENVIRONMENT

摘要

Visualization and assessment of facial skin aging attributes requires images captured using both uniform and directional illumination. Historically, facial skin imaging is accomplished using closed imaging environments for illuminating the subject with uniform diffused lighting, while eliminating unwanted effects of ambient light. A closed environment is also ideal for fluorescence and absorption imaging, as it simplifies analysis algorithm development and allows evaluation of the subject's entire face. However, direct illumination and secondary reflections may reduce contrast of skin topographical features.
