Systems and methods for analyzing stained fabric articles

A method for analyzing stained fabric articles, wherein the method comprises:

• providing a stained fabric article including a foreign oily substance disposed in and/or on the fabric article;
• capturing at least one image of the stained fabric article using a three-dimensional imaging device, wherein the at least one image is captured in the absence of a colored dye added to the foreign oily substance in and/or on the fabric article;
• processing the at least one image using a contrast function to produce a processed data set and
• producing one or more of a processed image or a quantitative data set representative of oily substance presence in a viewing area of the three-dimensional imaging device based upon the processed data set
• laundering the stained fabric article after capturing the at least one image of the stained fabric article to produce a laundered article;
• capturing at least one image of the laundered article using the three-dimensional imaging device;
• processing the at least one image of the laundered article using the contrast function to produce a processed data set of the laundered article;
• and
• producing one or more of a processed image or a quantitative data set representative of oily substance presence in the viewing area of the three-dimensional imaging device based upon the processed data set of the laundered article.
