1. A method for identifying a skin feature color contrast and/or a skin feature intensity contrast value, comprising:
a. obtaining at least one image of a subject; wherein the at least one image of the subject is a color image or a grayscale image;
b. extracting a skin feature image from the at least one image of the subject to obtain an extracted skin feature image, wherein the extracted skin feature image is a black and white image and identifies a boundary of the at least one skin feature;
c. superimposing the at least one image of the subject and the extracted skin feature image to identify at least one of the following within the boundary of the at least one skin feature: a skin feature color; or intensity of the at least one skin feature;
d. defining an adjacency area radially from the identified boundary of the at least one skin feature in the extracted feature image; wherein the defined adjacency area is a black and white image;
e. superimposing the at least one image of the subject and the defined adjacency area to identify at least one of the following: an adjacency area color; or intensity of the adjacency area; and
f. comparing at least one of the following:
the skin feature color and the adjacency area color to identify the skin feature color contrast; or
the intensity within the identified boundary and the intensity of the adjacency area to identify the skin feature intensity contrast value.
