Abstract:

We compute the Euler equations of a functional useful for simultaneous video inpainting and motion estimation, which was obtained in $[17]$ as the relaxation of a modified version of the functional proposed in $[16]$. The functional is defined on vectorial functions of bounded variation, therefore we also get the Euler equations holding on the singular sets of minimizers, highlighting in particular the conditions on the jump sets. Such conditions are expressed by means of traces of geometrically meaningful vector fields and characterized as pointwise limits of averages on cylinders with axes parallel to the unit normals to the jump sets.
