Dynamic radiografic testing with the use of screening raster and digital image processing

The effect of such operations of image digital processing as dimer median filtration, levelling of the average value of opacity, filtration of lower and upper spatial frequencies on the quality of an X-ray image of a moving plastic product pre-- pared using a pulsed X-ray apparatus and a stable screening raster, is investigated. It is shown that the use of screening rasters for dynamic radiography with the following image digital processing by means of procedures of image permits to obtain images of investigated object of satisfactory quality
