Abstract
This paper presents a comparative study of multi-look approaches for de-noising phase maps from digital holography experiments. A database of 160 simulated phase fringe patterns with 8 different phase fringe patterns with certain fringe diversity were computed. For each fringe pattern, 20 realistic noise realizations are generated in order to simulate a multi-look process with 20 inputs. A set of 37 de-noising algorithms were selected and processed for each simulation. The results demonstrate that the two-dimensional windowed Fourier transform filtering exhibits the best performance in all cases.
