Abstrakt

This study deals with the automated segmentation of radiographic pictures, which is an important task in the process of automatic weld defect recognition. Generally, the process of radiogram binarisation is controlled by several parameters, the selection of which is a very demanding task that strongly influences the overall results. This paper presents an algorithm for an automatic selection thresholding method as well as its parameters using genetic programming techniques. The proposed method could be applied as part of the industrial process of automatic radiogram analysis. 

Optymalizacja procedury progowania radiogramów

Streszczenie

Praca porusza zagadnienia związane z procesem automatycznej obróbki i analizy cyfrowych zdjęć radiograficznych połączeń spawanych. W pracy zaprezentowano metodę doboru parametrów progowania zdjęć radiograficznych celem ekstrakcji obiektów potencjalnych niezgodności spawalniczych. Dobór optymalnych parametrów procedury progowania dokonywany jest za pomocą techniki programowania genetycznego.
