Abstract
A process for measuring skin ashing is provided. The process comprises selecting a desired skin testing area and acguiring an image of the area using x-polarization technique. The image is analyzed by obtaining a light distributing image, storing the difference between this image and the original image and using a differential in intensity to define ashing.
