Abstract
Due to recent advances in micro-electronics, many digital image enhancement techniques can now be readily applied at standard video-rates using commercially available hardware. These techniques are being increasingly applied in the field of nondestructive testing, in particular to methods that generate TV-type video images, such as real-time radiography and pulse-video thermography. The latest techniques used by the National NDT Centre at Harwell are described and are illustrated by examples from three application areas.
