I. Introduction
Each year, more than one million people suffer burn injuries in Canada and the United States [15]. Accurate rating of scar condition is needed in order to design an effective treatment plan. Scar rating in clinical settings is done using the Vancouver rating scale or its variants by which experts assess the vascularity, pigmentation, pliability, and size of scars [16], [22]. These rating methods suffer from their subjective nature and low consistency among rates. There is a strong need for a quantitative and objective scar rating method based on the biophysical properties of skin tissue [14].
