Computer Vision Algorithms for Yield Mapping in Specialty Farms
… of being completely automated. Specialty crops (tree fruit, flowers, vegetables, and nuts) are excellent candidates for similar automation as they have high monetary value, high management cost and high variability in growth. An important capability for both precision agriculture and phenotyping …
