Classification: CPC G | IPC G

Claim 9:
10. A system for fatigue crack detection, comprising:
a memory device comprising memory configured to store computer-readable instructions thereon; and
at least one processing device comprising processing circuitry configured, through execution of the computer-readable instructions, to:
capture a first image of a structure at a first time;
capture a second image of the structure at a second time;
perform a feature-based image registration through a rigid-body transformation to align features of the second image with the first image;
perform an intensity-based image registration through a non-rigid transformation to further align features of the second image with the first image;
determine a registration error map based on a comparison of the first image and the second image; and
perform edge-aware noise reduction on the registration error map.
