As seen in Figure. 12(a) it reveals an image where the elliptical convex areas are in green shade and the elliptical concave areas are in red shade while as seen in Figure. 12(b), it shows how a thresholding has been applied to separate the areas with high values for curvature, which correlate to the area of interest: the nose is the most convex regions of the face and the eye sockets are the most concave regions of the face. In Figure 13, the elliptical convex regions and the elliptical concave areas show up green and red color, respectively, over those face image \cite{gonzalez2014kinect}.
