Abstract

We propose and analyze a finite-difference discretization of the Ambrosio-Tortorelli functional. It is known that if the discretization is made with respect to an underlying periodic lattice of spacing ffi, the discretized functionals Gamma-converge to the Mumford-Shah functional only if delta
