A new fully automated analysis and classification method for automatic defect recognition (ADR) in X-ray images is presented and compared to traditional methods. It is shown, that the new method called Trained Median Filter (TMF) - overcomes all the weaknesses of established methods. Even flat defects in structured areas that tend to decompose are found reliably. In conclusion a performance estimation demonstrates the real-time capability in a batch testing system.en1435-4934200210NDT.netTechnikMedizinJournal Articlehttps://www.ndt.net/search/docs.php3?id=1539Other
