Image processing of industrial radiographs
Abstract
The report documents the data accumulated as a result of a survey of various approaches to radiographic image processing conducted by the Air Force Materials Laboratory. A detailed discussion of each method is presented, together with the results of an evaluation of several typical systems using a set of control radiographs. Systems evaluated include electronic or electromechanical, using both analog and digital techniques as well as photographic approaches to image processing.
