Abstract
In this paper we study the
(

)
{(\mathrm{BV},L^{p})}
-decomposition,
p
=
1
,

{p=1,2}
, of functions in metric random walk spaces, a general workspace that includes weighted graphs and nonlocal models used in image processing. We obtain the Euler-Lagrange equations of the corresponding variational problems and their gradient flows. In the case
p
=
1
{p=1}
we also study the associated geometric problem and the thresholding parameters describing the behavior of its solutions.
