White noise with the image files concerned (naht1.bmp... naht20.bmp)
acts it thereby around a picture pile of 20 pictures (raw data 615 x
416), which comes from a picture recording system, whatever conveys
apart from the actual picture signal disturbances. Therefore to the
actual signal white noise (thus with average value 0) as disturbance
with the picture is returned the delivery. Radiographs of a welding
seam are shown with those errors in the material structure as bright
points on dark background to be illustrated. Use now your knowledge
for picture improvement in such a way that material defects in the
welding seam (round bright structures in the dark display space) in
the picture become recognizable. Indicate they the number of
recognized material defects.
