Blowhole Detection Based on Bidirectional Enhancement and Omnidirectional Analysis for X-Ray Inspection of Castings

Figure 5

The 3D surface plots with the background eliminated and the 3D model fitting result images of typical segments: (a–d) images of the real defects and (e–h) images of the false defects. The images on the left of each part are the 3D surface plot with the background eliminated. The images on the right of each part are the 3D model fitting result images.
