Hi @NotSam
There are two types of “empty” images:
- Null Images: Null images are those that have been labeled, but they have been labeled as having no annotations. Basically, null images means Roboflow was told that there’s nothing in the image.
- Unannotated Images: Unannotated images are unlabeled images. Those that haven’t been told anything by the user.
Unannotated images are omitted automatically. They are not added to your dataset, and live in either the Unassigned, Annotating or Review (not applicable for some workspaces).
Null images are those that are in the dataset and will not be omitted automatically. You can filter those out entirely or by percentage here:
Hope this helps!
