In this paper we consider a class of discrete variational models derived from a theory of Geman and McClure and study their asymptotic behavior when their stepsize tends to zero. It is shown that a result of {gamma} -convergence toward a certain functional holds true if a characteristic parameter of these models obeys a well-defined dependence law upon the stepsize. Under this condition the {gamma} -limit is a modified form of the Mumford-Shah functional.
