Abstract

This is the third and final installment of a three-part article on detection and classification of discontinuities appearing in radiographic images of welds. The present installment is the continuation of the section on unsupervised pattern recognition. In this work, the authors present the phenomenological analysis of the pattern profiles of weld discontinuities that resulted from the adaptive resonance theory (ART) networks that were carried out. It is recommended that the previous parts of this article (de Padua et al., 2007a; 2007b) be read before the present installment.
