The authors progressively altered a DINOv2-style training recipe, testing global-to-global alignment, local-to-global alignment and iBOT masked patch prediction separately and in combination.
Two same-image global views drive semantic structure in DINO models
Controlled retraining experiments indicate that global-view alignment creates the semantic foundation, while masked patch prediction mainly refines it.

In one line
DINO-style semantic structure comes from aligning two geometrically distinct global crops of the same image; masking refines it, while local crops mainly improve classification.
