Inside the dataset

A small pattern.
A much larger drawing.

Start with a hatch example, then find regions with the same pattern. Explore real drawings below to see the query, a reviewed match and reviewed nonmatches.

Annotations, not predictions.These boxes identify reviewed example regions. Areas outside the reviewed regions are unknown—not assumed to be background or nonmatches. This gallery reports no model performance.

What is reviewed?

A reviewed match does not certify every similar-looking region on the page. A reviewed nonmatch does not turn the rest of the page into background. Only the released known regions are scored; supplied query and context boxes are excluded.
