- The page says uploaded photos are measured and discarded in the browser; its demo includes a synthetic canopy with known leaf area.
Field notes
The browser demo exposes controls for photo and synthetic-canopy inputs, lens selection, and zonal thresholds. Its stated defaults include a 70° analysis limit, a blue-channel measurement, and gamma 0.85; the page cautions that other masks and cameras may call for the Python tool. The Python package lists numpy, pandas, and Pillow as its requirements.
