Vein density measurement using sizing transforms. (A) The ROI from Figure 2B shown after applying a sizing transform; the lighter shades correspond to larger balls that fit into foreground areas. (B) An expanded view of the same areole as is shown in Figure 2C. (C) Another view of the expanded area showing a pixel surrounded by a ball with a diameter of 31 pixels. (D) The distribution of ball sizes for the entire ROI. The arrow indicates the location in this distribution of the pixel identified in (C).
