Abstract: Systems and methods are described for generating three-dimensional (3D) image models of skin surfaces. An example method includes analyzing, by one or more processors, a plurality of images of a portion of skin of a user, the plurality of images captured by a camera having an imaging axis extending through one or more lenses configured to focus the portion of skin, wherein each image of the plurality of images is illuminated by a different subset of a plurality of LEDs configured to be positioned at a perimeter of the portion of skin. The example method may further include generating, by the one or more processors, a 3D image model defining a topographic representation of the portion of skin based on the plurality of images; and generating, by the one or more processors, a user-specific recommendation based on the 3D image model of the portion of skin.

Abstract: Methods and apparatuses are disclosed for capturing and analyzing images of human hair, particularly of a human scalp. Implementations described for capturing images at multiple locations on the scalp, detecting follicles and hairs, and generating a variety of measurements indicative of the condition of the hair, including the number and density of follicles, hair widths, inter-follicular distances, and the number of hairs per follicular unit, among other possibilities. Measurements can be compared among scalp locations, as well as among sequentially obtained images of the same location. A dermatoscope attachment for contact imaging of the scalp is also disclosed. The attachment may include polarizers enabling cross polarized imaging of the scalp.

Abstract: Methods and apparatus are disclosed that assist a user such as a doctor to track changes that occur in features of a subject's skin as the skin features evolve over time. Such a tracking can be done for images captured under different imaging/lighting modalities, by different image capture devices, and/or at different points in time. Methods and apparatus to automatically identify and track the unconstrained appearance/disappearance of skin features are disclosed.

Abstract: Embodiments of a method for performing image analysis include accessing a digital image of a subject, the digital image comprising a portion of a target substrate of the subject, the digital image comprising a portion of a calibration device; detecting a position of the calibration device by searching the digital image for a predetermined background color; detecting a plurality of color chips on the calibration device; mapping a position of the plurality of color chips on the digital image, each of the plurality of color chips comprising a predetermined chip color; comparing at least a portion of the plurality of color chips with a predetermined color standard; and altering the digital image, based on the comparison, to provide consistent image parameters with other images of the subject.
