Abstract

Two single-image methods designed for a fringe image modulation extraction are described. They are based on the two dimensional continuous wavelet transformation (2D CWT) and two dimensional Hilbert transform (2D HT) aided by bidimensional empirical mode decomposition (BEMD). Optimization of the proposed methods is described. Numerical simulations designed to test their performance are presented. Both approaches applicability is verified by processing experimental resonance vibration patterns acquired using time-average interferometry. Obtained results agree well with ones obtained using temporal phase shifting method.
