  • Methods and systems for imaging and modeling skin using polarized lighting
    Patent number: 8823934
    Abstract: A method for imaging skin includes illuminating a subject with at least one light source of one or more light sources. The method includes acquiring a first image of the subject in a first polarization with a respective photodetector of one or more photodetectors configured to acquire images of the subject as illuminated by the at least one light source, and acquiring a second image of the subject in a second polarization with the respective photodetector. The method also includes generating a subtraction image by subtracting at least a portion of the first image from a corresponding portion of the second image, and providing at least a portion of the subtraction image for display.
    Type: Grant

  • Systems and methods for determining a surface profile using a plurality of light sources
    Patent number: 8804122
    Abstract: A method for determining a surface profile of subject's skin includes illuminating the subject with light from a plurality of light sources. The plurality of light sources having distinct colors is configured to illuminate the subject from distinct locations. A multi-color image of the subject is obtained. The multi-color image includes respective values corresponding to respective intensities of light of respective colors for each region of the subject. A surface profile of the subject is determined in accordance with the respective values corresponding to the respective intensities of light of the respective colors.
