Abstract	Magnetic Flux Leakage (MFL) is a commonly used technology for non destructive evaluation. In this study a coarse to fine approach is proposed to interpret MFL measurements. Defect profile inferred from a Gaussian Process model was used in a unconstrained non-linear optimiser to further improve the accuracy. This framework was tested on 100 year old 600mm diameter cast iron pipes. The ground truth extracted using a 3 − D laser scanner showed a good agreement with the generated remaining wall thickness profile . With the reliable interpretations, this approach can be successfully used in the decision making of the asset maintenance process.
