A Novel SFP Extracting/Tracking Framework for Rigid Microstructure Measurement

Figure 1

Structural feature points on a rigid 3D microstructure (a) and the failed detecting and matching results of some popular methods (b), (c), and (d). These results failed to locate precisely on the positions of SFPs.
