    • Automated thresholding in radiographic image for welded joints 

      Haniza, Yazid; Hamzah, Arof, Dr.; Hafizal, Yazid (Taylor & Francis, 2012)
      Automated detection of welding defects in radiographic images becomes non-trivial when uneven illumination, contrast and noise are present. In this paper, a new surface thresholding method is introduced to detect defects ...
