Abstract :
Partial least square regression is applied for the processing of eddy current testing data used for the reconstruction of the shape parameters of cracks. The procedure is applied for cracks having very small spatial extensions. It is found that the reconstruction of the area of such cracks is considerably more robust than the reconstruction of their length and depth parameters.
