No ground truth on this frame
Accuracy cannot be scored here until a human draws truth. Model runs will still produce counts and you can eyeball them in the viewer, but precision, recall and F1 stay blank — an unscored count is an opinion, not evidence.Frame metadata
Everything downstream — every chart, every export, every number quoted to a panel — is indexed on these figures.

A 10 mm plant spans 1.7 px hereDensity / cover only
At ~1.7 px across, an individual plant is 2–3 pixels. Percent cover or density per m² is the only measure that survives review — individual counts at this GSD are not defensible.
