How to define "Require Novel Class" in paper

OV-DETR indeed use pseudo labels, as you can find in the Section B of OV-DETR's Appendix and their implementations.

We follow the steps of ViLD, pre-training a detector with the base classes to predict object proposals that may cover the novel classes.
