Conventional crop-spraying with herbicide to kill weeds among a crop wastes a lot of the herbicide and raises environmental concerns. A smart crop sprayer might identify weeds growing through the crop and spot spray only the unwanted plants. Work from a team in China published in the International Journal of Computational Science and Engineering, looks at the real-time segmentation of a cornfield to detect weeds that could be used to control such a smart crop-sprayer.
