Estimating wound volumes from scanner data

This paper considers how data from combined 3D depth maps and colour images can be used to estimate the volume of a wound - a procedure which may be important to its successful treatment. The colour image is used to segment the data into wound and non-wound areas. We then use the area of good skion surrounding thye wound to fit a hypothetical surface going across the wound, telling us where the skin surface would have been without a wound. Finally, data in the wound area is used to estimate the depth of the wound relative to this hypothetical surface, from which the volume of the wound can be computed. The main new contribution of this paper lies in the surface fitting method described. At pesent only a methodology is given, as practical tests have not been carried out.
