The authors investigate the applicability of statistical techniques for defect detection in radiographic images of welds. The defect detection procedure consists of statistical hypothesis testing using several nonparametric tests. A comparison of rules derived for image thresholding for a given level of false alarm is presented. Circular defects such as cavities and voids are considered as well. Numerical experiments with real data are performed.
