Abstract
This paper presents an effective method to automatically extract welds fromdigitised radiographs. An algorithm was developed to locate and extract welds from theintensity profiles taken across the image by using a simple graphical analysis method. Thealgorithm proposed was successfully applied to extract welds from 45 digitised weldradiographic images. The proposed method of weld segmentation was found work well withradiographs having non-Gaussian intensity distribution across the weld region.
