ABSTRACT:
Quantitative characterization of a crack detection analysis method is achieved by determining the detection sensitivity and background noise produced by the analysis method by suitably processing images obtained from one or more control specimens prepared by the method and subjected to appropriate and optimized conditions of illumination. In addition, the crack detection analysis method is optimized by looking for the parameters which influence the method and determining the value thereof which maximizes detection sensitivity and minimizes background noise.
