CA 2678551

A novel method and system is disclosed to realistically simulate the progress or worsening of facial skin features that contribute to the overall look and condition of the skin. The method utilizes two close-up photographs of the face, one is captured with a digital camera in standard white light, and the other is captured with the same camera in UV light. Then, the method processes these images to simulate the progress or worsening of the major skin features: hyperpigmented spots, wrinkles and small texture features. The worsening of these features simulates facial skin aging due to prolonged exposures to sunlight, biological aging or degradation of the skin health. The progress of these features simulates the improvement of facial skin in terms of overall look and healthiness as though the patient has gone through a treatment. Therefore, the present invention discloses a series of methods that are useful in dermatology, cosmetics and computer animations.

L'invention concerne un nouveau procédé et un nouveau système de simulation réaliste de l'amélioration ou de la dégradation des caractéristiques de la peau du visage contribuant à l'aspect et à l'état général de la peau. Ledit procédé consiste à utiliser deux photographies portraits du visage, l'une capturée à l'aide d'un appareil photo numérique à la lumière blanche standard, l'autre capturée à l'aide du même appareil photo numérique à la lumière UV. Le procédé consiste ensuite à traiter ces images pour simuler l'amélioration ou la dégradation des caractéristiques principales de la peau: les taches hyperpigmentées, les rides et les petits défauts de texture. La dégradation desdites caractéristiques simule le vieillissement de la peau du visage causé par des expositions prolongées au soleil, le vieillissement biologique ou la dégradation de l'état de la peau. L'amélioration de ces caractéristiques simule l'amélioration de l'aspect et de l'état général de la peau du visage comme si le patient avait été soumis à un traitement. La présente invention concerne une série de méthodes utilisées en dermatologie, en cosmétique et dans des animations sur ordinateur.
