Abstract:
1. A method for detecting skin conditions associated with a skin of a subject, the method comprising: activating a first light source to illuminate the skin, wherein the first light source is disposed at a first light source angle with respect to the skin; capturing a first plurality of images of the skin while the skin is illuminated by the first light source, from a first plurality of camera angles with respect to the skin; activating a second light source to illuminate the skin, wherein the second light source is disposed at a second light source angle with respect to the skin; capturing a second plurality of images of the skin while the skin is illuminated by the second light source, from a second plurality of camera angles with respect to the skin, wherein the first plurality of camera angles are at least partially different from the second plurality of camera angles; evaluating, by a computing device, image data from the first plurality of images and image data from the second plurality of images to identify properties corresponding to each of a plurality of points on the skin for each of the first and second light source angles to calculate a subsurface transfer function for the skin, wherein the subsurface transfer function describes one or more subsurface properties of the skin; and comparing, by a computing device, the subsurface transfer function to subsurface transfer functions in an electronic library of subsurface transfer functions and corresponding skin conditions to identify a skin condition for the subject, wherein the electronic library comprises one or more subsurface transfer functions corresponding to one or more melanoma skin conditions, and wherein the electronic library comprises one or more subsurface transfer functions corresponding to one or more other known skin conditions.
