Abstract Scope |
X-ray computed tomography (XCT) enables non-destructive 3D characterization of material microstructures and defects. The Terabyte-scale dynamic XCT datasets output from these imaging modalities, however, remain a challenge to analyze. To solve this, we developed a spatiotemporal scene graph representation to encode objects, relationships, and evolution in large-scale 4D XCT data of AlMg undergoing stress corrosion cracking (SCC). The graph nodes represent segmented cracks, precipitates, and pitting, with attributes capturing morphological metrics. Edges encode spatial relationships between defects and microstructural features. Dynamic edges connect defect instances across time steps, explicitly modeling crack growth and microstructural evolution. The graph formulation further allows integration of deep learning techniques and relational reasoning between defects and microstructure. This establishes scene graphs as a flexible and powerful representation for exploiting structure in massive tomographic imaging data. |
