说明：[K,H,P1,P2] = surfature(X,Y,Z) returns the gaussian curvature of a surface (K), mean curvature (H), and principal curvatures (P1,P2). The inputs (X,Y,Z) are 2D arrays corresponding to the surface being analyzed. Example [X,Y,Z] = peaks [K,H,P1,P2] = surfature(X,Y,Z) surf(X,Y,Z,H, facecolor , interp ) set(gca, clim ,[-1,1])

说明：This article presents a novel scale- and rotation-invariant detector and descriptor, coined SURF (Speeded-Up Robust Features). SURF approximates or even outperforms previously proposed schemes with respect to repeatability, distinctiveness, and robustness, yet can be computed and compared much faster.

说明：a real-time 3D pointing gesture recognition algorithm for natural human-robot interaction (HRI). The recognition errors in previous pointing gesture recognition algorithms are mainly caused by the low performance of the hands tracking module and by the unreliability of the direction estimate itself, therefore our proposed algorithm uses 3D particle filter for achieving reliability in hand tracking and cascade hidden Markov model (HMM) for a robust estimate for the pointing direction. When someone enters the field of view of the camera, his or her face and two hands are located and tracked using the particle filters. The first stage HMM takes the hand position estimate and maps it to a more accurate position by modeling the kinematic characteristics of finger pointing.
