Cover image by Linqi Zhu on pages 109–124. The cover connects geological CO₂ storage with AI-assisted analysis of pore-scale images. Beneath the injection site, an enlarged rock volume transitions from micro-computed tomography imagery on the left to a segmented 3D representation on the right, where blue and orange distinguish fluid phases within the gray rock matrix. SAMamba3D adapts the Segment Anything Model for generalizable 3D segmentation across diverse rocks and imaging conditions, supporting quantitative characterization of fluid saturation, connectivity, and interfacial geometry for multiphase-flow studies and applications such as subsurface CO₂ storage.
