A new procedure, free from human assessment that automatically grades some facial skin structural signs. Comparison with assessments by experts, using referential atlases of skin ageing

OBJECTIVE: To develop an automatic system that grades the severity of facial signs through 'selfies' pictures taken by women of different ages and ethnics. CONCLUSION: Ce systeme de scorage automatique, encore en developpement, semble offrir une nouvelle approche dans la description quantitative de signes du visage, independante de l’œil humain, dans de nombreuses applications, comme la personnalisation, a visee cosmetique ou dermatologique, dans le suivi de certaines strategies medicales de l'antivieillissement cutane. RESULTS: The system appears weakly influenced by lighting conditions or facial expressions (coefficients of variations ranging 10-13% for most signs) and leads to global agreements with experts' assessments, even showing a better reproducibility on some facial signs. CONCLUSION: This automatic scoring system, still in development, seems offering a new quantitative approach in the quantified description of facial signs, independent from human vision, in many applications, being individual, cosmetic oriented or dermatological with regard to the follow-up of medical anti-ageing corrective strategies.
