Research & Teaching Experience
Sampling and perfect reconstruction of signals with Finite Rate of Innovation (FRI) [ Vetterli et al 02]
Signals: Bilevel-convex polygons, distribution of Diracs, 2-D polynomials with polygonal boundaries, quadrature domains (circles, ellipses, cardioids etc).
Sampling kernels: Any function that reproduce polynomials (B-splines, and scaling functions from wavelet theory).
Reconstruction: Annihilating fitter method (Prony’s method), Complex-moments, Lattice theory (directional derivatives), Radon transform.
