Patent Images
1. A method for analyzing lip conditions associated with a subject, comprising:
- acquiring a first white-light image and a first UV image of the lips of a subject, each of the first white-light and UV images include a plurality of pixels, each pixel in the first UV image corresponding to a respective pixel in the first white-light image;
generating a lip mask based on data in the white-light image, said lip mask having a plurality of elements each corresponding to a respective pixel in the first white-light image and the first UV image, wherein each of the plurality of elements is assigned a value;
examining properties of each pixel in at least the first UV image;
identifying lip-pixels in the UV image, wherein said identifying step comprises;
for each pixel in the first UV image, determining if the pixel is a lip pixel by looking up the value in a corresponding element in the lip mask; and
obtaining results associated with at least one lip condition using information in the lip-pixels in the UV image.

Abstract
Systems and methods are provided for analyzing lip conditions using digital images. The method comprises acquiring a white-light image and an ultraviolet (“UV”) image of the lips of a subject, each of the white-light and UV images including a plurality of pixels and each pixel in the UV image corresponding to a respective pixel in the white-light image. The method further comprises identifying lip-pixels in the white-light and UV images, and obtaining results associated with at least one lip condition using information in the lip pixels in the first white light and UV images.
