In this paper, a new surface thresholding method is introduced to detect defects in radiographic images of welding joints. In the first stage, several image processing techniques namely fuzzy c means clustering, region filling, mean filtering, edge detection, Otsu's thresholding and morphological operations method are utilised to locate the area in which defects might exist. This is followed by the implementation of inverse surface thresholding with partial differential equation to locate isolated areas that represent the defects in the second stage. The proposed method obtained a promising result with high precision. 2013-05-15T06:56:11Z 2013-05-15T06:56:11Z 2012 Article Nondestructive Testing and Evaluation, vol. 27 (1), 2012, pages 69-80 1477-2671 (Online) 1058-9759 (Print) 10.1080/10589759.2011.591795 http://www.tandfonline.com/doi/full/10.1080/10589759.2011.591795#.UUQNf0rTG4s http://hdl.handle.net/123456789/25489 en Taylor & Francis |
