and become invariant to changes in location, lighting, backgrounds, or other factors. Devising high-throughput systems is necessary to capture hundreds of thousands of images of weeds at various growth stages while affected by field-like conditions. A network of agronomic, hardware, and software engineers is needed to automate large scale image collection.

Labeling is Time Consuming

Pixel-wise labels must be accurate. The process of labeling by hand can take minutes to hours even when using third-part annotation tools. Many have reported the high time requirement needed for labeling images of weeds.
