Abstract

A new robust and fast method for non-interactive line segmentation of interferograms is proposed. Fringe contours are represented as a set of polygons using a new technique for contour approximation. The method has been developed for application in interferometry with continuously deforming objects. Its application to real-time holographic interferometry in nondestructive testing is shown.
