Counting seeds, sprouts and produce from images
Counting is the measurement people most often do by hand and most often get wrong at scale — miscounts compound quietly across a trial. These guides cover what a smartphone can count reliably, where automated germination counting still needs a human check, and what counting at volume revealed in a real warming experiment.
Climate Impacts on Oak Germination and Early Development: What a 2,112-Acorn Warming Experiment Reveals
A common-garden warming experiment on sessile and pubescent oak shows that a seed's climate of origin — not warming alone — drives germination, survival, and early growth. Leaf area was measured with the Petiole Pro app to derive specific leaf area.

Counting Round Objects with a Smartphone: Blueberries, Seeds, Nuts and Computer Vision
How a smartphone counts round objects — blueberries, soybean and chickpea seeds, peanuts, beans, grapes — using computer vision and light deep-learning models. Get count, average size, and standard deviation from one photo, why 87% accuracy is often enough, and why a calibration plate is the rule for real measurements.
