Edge detection uncertainty in fringe analysis

Fringe image processing during gauge block measurement is usually performed with some sort of edge detection algorithm, used to find the centers of fringes. This paper addresses potential differences in measurement results that arise due to the use of different edge detection algorithms. Edge detection algorithms compared in this paper include simple image binarization, Prewitt and Sobel filters, Canny algorithm, and an algorithm developed at LFSB.
