Abstract
Technologies generally applicable to detecting skin conditions are disclosed. A computer graphics scanning apparatus may be configured to capture skin image data, and use the captured skin image data to calculate a subsurface transfer function for the skin, which may identify subsurface properties of the skin. The identified subsurface properties may be correlated to one or more skin conditions for medical and/or cosmetic treatment diagnosis.
Claims25
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;
- while the skin is illuminated by the first light source, capturing a first plurality of images of the skin 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;
- while the skin is illuminated by the second light source, capturing a second plurality of images of the skin 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 light source angles;
- evaluating the first plurality of images and 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
- algorithmically identifying a skin condition corresponding to the one or more subsurface properties of the skin.
A device configured to detect skin conditions associated with a skin of a subject, the device comprising:
- a plurality of light sources, wherein each of the plurality of light sources is located at a different light source position;
- a plurality of cameras, wherein each of the plurality of cameras is located at a different camera position;
- an image capture controller configured to selectively activate each of the plurality of light sources in a predetermined sequence, and configured to selectively capture images of the skin at each of the plurality of cameras when illuminated by one or more activated light sources;
- and
- a processor configured to calculate a subsurface transfer function for the skin using image properties corresponding to each of a plurality of points on the skin in each of the captured images, wherein the subsurface transfer function describes one or more subsurface properties of the skin;
- wherein the processor is configured to algorithmically identify a skin condition corresponding to the one or more subsurface properties of the skin.
A computer readable medium having computer executable instructions for detecting skin conditions from data comprising a plurality of images of a skin from a plurality of different camera positions, and using a plurality of light sources at a plurality of different light source positions such that the data comprises images from each of the plurality of different camera positions for each of the plurality of different light source positions, the instructions comprising:
- instructions to calculate a subsurface transfer function for the skin using image properties corresponding to each of a plurality of points on the skin in each of the plurality of images corresponding to each of the plurality of different light source positions, wherein the subsurface transfer function describes one or more subsurface properties of the skin;
- and
- instructions to algorithmically identify a skin condition corresponding to the one or more subsurface properties of the skin.
