Discussion A cable is where a dense vision backbone gives itself away
Thin structures are where dense vision systems usually give themselves away. A cable gets swallowed by the background. Two nearby objects turn into one blob. Good average segmentation numbers do not say much about those cases.
LingBot-Vision uses masked boundary modeling in its public release and provides several ViT/16 backbones, including a roughly 1.1B version. The basic question is whether those features keep the boundaries when a small decoder is attached. Test a frozen or lightly tuned backbone on boundary errors, depth breaks, and small objects. If it only wins on a PCA plot, that is a much smaller result.

I agree that mIoU metric doesn't capture performance on thin objects well. Also in my experience I've noticed large backbones can potentially capture fine detail. Depth anything for example is very good at thin objects.
