Why are we calling every bright line a scratch?

Our proposed FR10 cover-inspection images have moving bright lines labelled 'scratch'. I can't teach that distinction myself.

Give whoever judges the actual covers the marked image and the numbered cover together, otherwise you're asking them to identify a shiny line from another shiny line

The covers are numbered, fortunately. Our inspector found one groove but couldn't match the other bright lines.

Then keep that groove's location marked on the image separately from the changing reflections; can you show the same cover in both presentations?

Yes. We've removed three incorrect scratch labels. The confirmed groove disappears in one view, which needs sorting before training.

That's a useful pair to give the imaging person: same cover, known groove, one view hides it. Much easier to explain than 'the camera is inconsistent'
