4D hyperspherical harmonic (HyperSPHARM) representation of surface anatomy: A holistic treatment of multiple disconnected anatomical structures
Introduce HyperSPHARM for simultaneous parameterization of multiple disjoint objects. Show that HyperSPHARM possesses greater computational efficiency than SPHARM. Employ isotropic sampling along 4D sphere for HyperSPHARM interpolation. Employ HyperSPHARM as both a data smoothing and an object classification technique.
