Historical Evolution of Plant ID Tech
Plant identification apps trace to 2009's LeafSnap prototype at Columbia University, which used contour matching on 1,000 species. By 2017, AI leaps via convolutional neural networks pushed accuracies from 50% to 75%, per MIT's 2018 review. The 2022 explosion of free apps followed open datasets like iNaturalist, democratizing botany amid a 300% rise in urban gardening post-2020 lockdowns.
