Title: L1 Techniques for Three Problems in Nonlinear PDEs, Signal and Image Processing
Abstract: We address three different questions using L1 techniques.
(i) The vanishing viscosity limit of two-dimensional
nonlinear convection:L1 convergence follows from spectral dynamics (a
joint work with D. Wei).
(ii) Detection of edges in spectral information of
piecewise smooth data (a joint work with S. Engelberg and J. Zou); and
(iii) Recent results on image processing using (BV, L1)
multi-scale hierarchical decompositions (joint work with P. Athavale).
