We provide an approximation result for free-discontinuity functionals of the form
where is quadratic in the gradient-variable and is an arbitrary smooth Finsler metric. The approximating functionals are of Ambrosio-Tortorelli type and depend on the Hessian of the edge variable through a suitable nonhomogeneous metric .
