Fig. 4

Fig. 4. From: Shape-Based Classification of 3D Head Data.

Most relevant bins of 2D histograms of azimuth and elevation angles of surface normal vectors on 3D head mesh models. As the severity of flatness increases on the side of the head, the peak in the 2D histogram becomes more prominent

(a) Example of plagiocephaly. (b) Example of brachycephaly ((a) and (b) are from www.cranialtech.com). (c) Surface normal vectors of points that lie on a flat surface and will create a peak in the 2D angle histogram. (d) Surface normal vectors of points that lie on a more rounded surface and will be spread out in the histogram bins. (e) Azimuth and elevation angles of a 3D surface normal vector.
