Support Vector Machines and Eddy-Current Tests for Flaws Characterisation in Thin Metallic Plates

Abstract:- Eddy Current Techniques (ECT) for Non-Destructive Testing and Evaluation (NDT/NDE) of conducting materials is one of the most application-oriented field of research within electromagnetics. In this work, a novel approach is proposed to classify defects in metallic plates in terms of their depth starting from a set of experimental measurements. The problem is solved by means of a system based on wavelets approach extracting information on the specimen under test from the measurements and, then, implementing Support Vector Machines in order to determine its depth. Finally, Confusion Matrices (CMs) operators have been taken into account to improve the procedure
