The purpose of this paper is to present the relation between certain BMO-type seminorms and the total variation of SBV functions. Following some ideas of a recent paper by L. Ambrosio and G.E. Comi, we give a representation formula of the total variation of SBV functions which does not make use of the distributional derivatives. We consider an anisotropic variant of the BMO-type seminorm introduced in 2015 in a paper by J. Bourgain, H. Brezis and P. Mironescu, by using, instead of cubes, covering families made by translations of a given open bounded set with Lipschitz boundary.

Abstract
The purpose of this paper is to present the relation between certain BMO-type seminorms and the total variation of SBV functions. Following some ideas of a recent paper by L. Ambrosio and G.E. Comi, we give a representation formula of the total variation of SBV functions which does not make use of the distributional derivatives. We consider an anisotropic variant of the BMO-type seminorm introduced in 2015 in a paper by J. Bourgain, H. Brezis and P. Mironescu, by using, instead of cubes, covering families made by translations of a given open bounded set with Lipschitz boundary.
