Abstract: This paper presents a two-step algorithm to reconstruct parallel
cracks from ECT (eddy current testing) signals. The number, the approximate
locations and lengths of cracks are determined in the separation stage by
employing the eddy current imaging, and the profiles of cracks are obtained in
the reconstruction stage.
