Marked spinous processes, manual and automatic spine curve. (a) A grayscale image of the marked spinous processes, as drawn by the physician. Transition spine zones are marked by additional black horizontal lines; (b) an example of a manually determined spine curve (named the manual curve); (c) an example of an automatically determined spine curve based on the measured 3D shape of the back (named the automatic curve).
