Keypoints on 3D surfaces are points that can be extracted repeatably over a wide range of 3D imaging conditions. They are used in many 3D shape processing applications; for example, to establish a set of initial correspondences across a pair of surfaces to be matched. Typically, keypoints are extracted using extremal values of a function over the 3D surface, such as the descriptor map for Gaussian curvature. That approach works well for salient points, such as the nosetip, but can not be useddoi:10.1109/3dimpvt.2011.33 dblp:conf/3dim/CreusotPA11 fatcat:ivxfegkqqvbhta6tyjyjqhenj4
