　　In this talk we discuss the application of discrete gradient approaches for the solution of total variation regularised problems.We will show that the discrete gradient approach offers guaranteed energy decrease in every step,and could be particularily interesting for large-scale data as its computation may reduce to the solution of a sequence of 1D problems.
