Abstract

Techniques for the automatic detection of defects, such as cracks and cavities in radiographs of artillery shells, have been developed and demonstrated. Because the defect indications are subtle and ride on an intensity trend that varies greatly across the field, it is necessary to precede the detection algorithms by pre-processing steps which "flatten" the trend and emphasize the defects. The algorithms are described and examples of their performance are shown.
