Abstract

Abstract A review is provided of techniques for digital processing of noisy X-ray computed tomography and introscopy data that are represented by halftone images. The most hazardous crack flaws placed against a background with a wide range of brightness have been studied. Difference median and slit filters are proposed for processing such images.AbstractA review is provided of techniques for digital processing of noisy X-ray computed tomography and introscopy data that are represented by halftone images.
