We consider a variational scheme for the anisotropic (including crystalline) mean curvature flow of sets with strictly positive curvature. show that such condition is preserved by scheme, and we prove strict convergence in BV time-integrated perimeters approximating evolutions, extending recent result De Philippis Laux to setting. also uniqueness flat obtained limit.

part, based on a local decision. This approach has several We present a class of PDE-based algorithms suitable for key virtues. First, it contains only one enhancement paramimage denoising and enhancement. The techniques are applicaeter, which in most cases is automatically chosen. Second, ble to both salt-and-pepper gray-scale noise and full-image the scheme automatically picks the stopping cr...

we describe a variational problem on a surface under a constraintof geometrical character. necessary and sufficient conditions for the existence ofbifurcation points are provided. in local coordinates the problem corresponds toa quasilinear elliptic boundary value problem. the problem can be consideredas a physical model for several applications referring to continuum medium andmembranes.
