un seminario dal titolo:
“The
total variation denoising problem and Cheeger sets”
Abstract:
We will discuss
the ability of the total variation denoising problem to restore discontinuities
of the datum.On one hand this is related to the regularity of its solutions. On
the other, the explicit solutions of the problem also show that the
discontinuities may be smoothed at the points of the datum where the level lines
have a high curvature. The study of the explicit solutions leads us to the study
of Cheeger sets.Finally we will present some applications of Cheeger sets (with
respect to anisotropic perimeters) to image segmentation and image interpolation
problems.
