Figure 1

This figure shows a rasterstereographic measurement of a child. After the acquisition of the picture with a digital video camera, the image is then analysed by the computer, the anatomical landmarks are automatically detected, and transformed into a 3-D surface map of the back surface. The red colour on the back surface represents convex surface areas, while the blue colour stands for concave surface areas.
