AI Technical Summary
Existing technologies struggle to simultaneously improve the signal-to-noise ratio and resolution of crack attributes during crack enhancement, and the existing Frangi filtering method cannot capture the characteristics of thin and narrow crack lines.
A method based on the multi-scale Hessian matrix is adopted. By constructing the eigenvalues and eigenvectors of the Hessian matrix and combining them with the Frangi and Steger filtering functions, the crack attributes are regularized and enhanced, thereby refining and enhancing the cracks.
It improves the signal-to-noise ratio and resolution of post-stack crack properties, achieves finer and narrower crack lines, and simplifies the operation process, reducing the complexity of parameter adjustment.
