Misfit functional for recovering data in 2D ElectroCardioGraphy problems

This paper focuses on the inverse ElectroCardioGraphy problem which consists in recovering the electrical potential and flux on the heart from electrical potential on the body surface. An energy-like error functional introduced in Andrieux et al. [3] and a generalized least-squares method are performed in the context of this ill-posed problem of missing boundary data recovering. Numerical experiments with 2D domains highlight the efficiency of the proposed methods as well as their robustness in the model context.
