Most biological bodies are structured in the sense that they contain quite well-defined interfaces between regions of different types of tissue or anatomical material. Extracting structural information from medical or biological images has been an important research topic for a long time. Recently, much attention has been devoted to quite novel techniques(More)
Eddy-Current nondestructive evaluation of metal plates is of interest in a wide range of applications such as quality control in production lines or in-service inspection of industrial facilities. Both the tube and plate configuration have been studied earlier, by using different iterative optimization processes [1, 2]. These solutions are computation-heavy(More)
A new mean of solution of eddy current testing (ECT) inverse problems is presented herein. The aim is to characterize a defect within a generic work piece by inverting an ECT signal in a short time (less than 5 s on a standard PC). The inverse problem is solved using Particle Swarm Optimization (PSO). As inputs of this algorithm, a metamodel is used in(More)
