Crack parameters Estimator, based on MFL data analysis including Wavelet Transform on preprocessing step, are proposed. The 2D case was used to obtain only preliminary results and to demonstrate the feasibility of the approach. A further practical application to the magnetic inspection requires three-dimensional (3D) numerical models to construct an appropriate learning database for a NN classifier. To evaluate the generalization abilities of the NN classifier more extensively, a larger number of numerically obtained data is required. There is a further limitation to this analysis, namely that it have been concerned with modeling the crack without consideration being given to the magnetic behavior of the complete magnetizer. Future work includes more realistic crack shape, as well consideration of noise and vibration.
