Image Acquisition and Segmentation
Fluorescent dye penetrant inspection was used to locate a selection of cracks in a set of samples. The material around each crack was then cut away and the sample was imaged using an X-Tek BladeRunner system (Nikon Metrology).
The crack geometry was extracted from the X-Ray CT images using Simpleware ScanIP, with filtering and thresholding tools, primarily the 'Paint with Threshold' tool, used to obtain regions of interest.
