63 p, 650.6 KB Flux limited generalized porous media diffusion equations / Caselles, Vicent
We study a class of generalized porous media type flux limited diffusion equations and we prove the existence and uniqueness of entropy solutions. We compute the Rankine-Hugoniot condition on the jump set for solutions which are of locally bounded variation in space and time. [...]

22 p, 224.7 KB Convergence of the "relativistic" heat equation to the heat equation as c → ∞ / Caselles, Vicent (Universitat Pompeu Fabra. Departament de Tecnologia)
We prove that the entropy solutions of the so-called relativistic heat equation converge to solutions of the heat equation as the speed of light c tends to ∞ for any initial condition u0 ≥ 0 in L1 (RN ) ∩ L∞(RN ).

51 p, 383.2 KB The M-components of level sets of continuous functions in WBV / Ballester Nicolau, Coloma ; Caselles, Vicent
We prove that the topographic map structure of upper semicontinuous functions, defined in terms of classical connected components of its level sets, and of functions of bounded variation (or a generalization, the WBV functions), defined in terms of M-connected components of its level sets, coincides when the function is a continuous function in WBV.

30 p, 319.6 KB Line search multilevel optimization as computational methods for dense optical flow / Kalmoun, El Mostafa ; Garrido, Luis ; Caselles, Vicent ; Centre de Recerca Matemàtica
We evaluate the performance of different optimization techniques developed in the context of optical flowcomputation with different variational models. In particular, based on truncated Newton methods (TN) that have been an effective approach for large-scale unconstrained optimization, we develop the use of efficient multilevel schemes for computing the optical flow.
