Because of the complex nature of the considered images, and in order that the detected defect region represents the most accurately possible the real defect, the choice of thresholding methods must be done judiciously. In this paper, performance criteria are used to conduct a comparative study of four non parametric histogram thresholding methods for automatic extraction of weld defect in radiographic images.}, journal = {International Journal of Electronics and Communication Engineering}, volume = {1}, number = {9}, year = {2007}, pages = {1409 - 1413}, ee = {https://publications.waset.org/pdf/14872}, url = {https://publications.waset.org/vol/9}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 9, 2007}, }
