Abstract
Pipe condition assessment is critical to avoid breakages. Remote Field Eddy Current (RFEC) is a commonly used technology to assess the condition of pipes. The nature of this technology induces some particular noise into its measurements. In this paper, we develop a 3D simulation based on the Finite Element Analysis to study the properties of this noise. Moreover, we propose a ltering process based on a modi ed version of graph-cuts segmentation method to remove the in uence of this noise. Simulated data together with an exper imental data-set obtained from a real RFEC inspection show the validity of the proposed approach.
