Résumé : 

A welded structure must be inspected to guaranteethat the weld quality meets the design requirements to assure safetyand reliability. However, X-ray image analyses and defectrecognition with the computer vision techniques are very complex.Most difficulties lie in finding the small, irregular defects in poorcontrast images which requires pre processing to image, extract, andclassify features from strong background noise. This paper addressesthe issue of designing methodology to extract defect from noisybackground radiograph with image processing. Based on the use ofactives contours this methodology seems to give good results
