Summary
This assessment of radiographic image enhancement methods is part of an effort to determine the usefulness of radiographic inspection and the enhancement of radiographic images for monitoring or inspecting refractory-lined components of coal conversion systems. Enhancement offers the potential to bring out details that cannot be readily detected in original radiographs and to sharpen edges of bore contours so that one can more easily measure wall thicknesses and detect details such as cracks, voids, or inclusions. This report includes a review of image enhancement methods and the results of a quantitative test to evaluate image enhancement procedures for radiographs typical of a field environment. Direct measurements of a refractory cylinder wall thickness are compared with measurements made from radiographs and enhancements.
