Level Set Based Nonlocal Surface Restoration
Bin Dong, Jian Ye, Stanley Osher, Ivo D. Dinov · Multiscale Modeling and Simulation · 2008
In this paper we extend nonlocal smoothing techniques for image regularization in [G. Gilboa and S. Osher, Multiscale Model. Simul., 6 (2007), pp. 595–630] to surface regularization, with surfaces represented by level set functions. We test our algorithm on both phantom and observed surfaces, including city terrain and cortical surfaces.
