In this paper it is shown that any regular critical point of the Mumford-Shah functional, with positive de finite second variation, is an isolated local minimizer with respect to competitors which are sufficiently close in the $L^1$-topology.

Keywords: Free-discontinuity problems, Mumford-Shah functional, second variation, local minimality conditions
