1. A method for analyzing tissue healing, said method comprising: capturing an image including a tissue site; enabling a clinician to define multiple regions of the image of the tissue site, at least two of the regions of the image defining tissue types at different stages of tissue healing while in those healing stages; automatically comparing a first color associated with a first tissue type to imaged tissue at the tissue site to identify tissue of the first tissue type at the tissue site; automatically comparing a second color associated with a second tissue type to the tissue at the tissue site to identify tissue of the second tissue type at the tissue site; calculating areas of each of the first and second tissue types; and displaying the calculated areas of the first and second tissue types.
