Paper Abstract

The digital signal-processing method of fringe pattern extremal curves generation is presented. The method is based on 3D wavelet map computation. The correspondence between features of fringe pattern and 3D wavelet map of the same fringe pattern is described. For analysis, the Symmetrical Morlet wavelet is used. Wavelet map ridge detection algorithm is proposed. Fringe extremal curves obtained are used for fringe phase recovery that leads to possibility of 3D relief reconstruction.
