Our example images keep turning shiny patches into defects (presenting reflective components for surface inspection)

We're planning presenting reflective components for surface inspection, with Universal Robots UR5e presenting a brushed stainless trim plate to a fixed camera in a robot-presented camera station. Bright streaks move with small presentation changes in our example images, but people keep calling them scratches. We haven't commissioned the cell. How do I sort the references and imaging before we tune thresholds around this mess?

Were those scratches confirmed on the physical samples using your agreed appearance method? Start by linking each image to a sample and its inspection result

@IsabelBennett0735 I've found that some labels were assigned from the images themselves. The samples are still available, but those labels have no corresponding physical inspection results, making the reference circular.

Keep the image-only labels uncertain pending physical inspection. A controlled comparison of lighting and presentation can then investigate whether the moving streaks indicate reflection effects
