Paper Abstract

In this paper, a new technique to reduce speckle noise from interference patterns is proposed. This method, called cross absolute filter (CAF) is well suited to the case of noisy interferograms with phase error pixels. It is demonstrated that CAF performs better than classical median-type filters, preserving more subtle details.
