Multi‐step radiographic image enhancement conforming to weld defect segmentation

IET Image Processing, 2015
To improve the accuracy of automatic defect segmentation in radiographic non‐destructive testing and evaluation, the authors proposed a multi‐step radiographic image enhancement algorithm (MSRE) conforming to weld defect segmentation. In this algorithm, the requirement of defect segmentation is fully considered when enhancing a radiographic testing ...
