More eyes on the prize: open-source data, software and hardware for advancing plant science through collaboration

Abstract

Automating the analysis of plants using image processing would help remove barriers to phenotyping and large-scale precision agricultural technologies, such as site-specific weed control. The combination of accessible hardware and high-performance deep learning (DL) tools for plant analysis is becoming widely recognised as a path forward for both plant science and applied precision agricultural purposes. Yet, a lack of collaboration in image analysis for plant science, despite the open-source origins of much of the technology, is hindering development. Here, we show how tools developed for specific attributes of phenotyping or weed recognition for precision weed control have substantial overlapping data structure, software/hardware requirements and outputs. An open-source approach to these tools facilitates interdisciplinary collaboration, avoiding unnecessary repetition and allowing research groups in both basic and applied sciences to capitalise on advancements and resolve respective bottlenecks. The approach mimics that of machine learning in its nascence. Three areas of collaboration are identified as critical for improving efficiency, (1) standardised, open-source, annotated dataset development with consistent metadata reporting; (2) establishment of accessible and reliable training and testing platforms for DL algorithms; and (3) sharing of all source code used in the research process. The complexity of imaging plants and cost of annotating image datasets means that collaboration from typically distinct fields will be necessary to capitalise on the benefits of DL for both applied and basic science purposes.

Pots to Plots: Microshock Weed Control Is an Effective and Energy Efficient Option in the Field

“…The use of a flat-plate electrode is proven to be effective and efficient in a field setting. The system would fit well with robotic "spot weeders" equipped with weed recognition, which are increasingly available [65][66][67][68][69][70]. The flat-plate electrode requires accurate placement, which could be achieved by robots such as BoniRob [71], or other systems using using the delta arm configuration [72,73] or other accurate systems [74].…”
