Article

We study the influence of preliminary processing of digital X-ray images by their median filtering and brightness normalization by nonsharp masking and contrast enhancement on the basis of a logarithmictype model on the results of testing. Examples of experimental detection of defects in welds of various types are presented.

Keywords

Weld Filtering Contrast enhancement Segmentation of defects Logarithmic processing of images
