Two-dimensional continuous wavelet transform for phase determination of complex interferograms.
TL;DR: A phase determination rule is proposed according to the phase distribution continuity, and a frequency-guided scheme is employed to obtain the correct phase distribution following a conventional 2D-CWT analysis.

Two-dimensional continuous wavelet transform algorithm for phase extraction of two-step arbitrarily phase-shifted interferograms
TL;DR: A two-dimensional continuous wavelet transform algorithm that has a remarkable ability to accurately and automatically extract full-field phase distribution from two phase-shifted interferograms where they may contain arbitrary and unknown phase shift.

Parameter discretization in two-dimensional continuous wavelet transform for fast fringe pattern analysis
TL;DR: The cover map is introduced to speed up the 2D-CWT analysis by discretizing the continuous dilation and rotation parameters and helps substantially reduce the processing time without affecting the analysis accuracy.
