Haipeng Yu, a UF/IFAS assistant professor of animal sciences and quantitative geneticist, uses computer vision (CV) to help livestock producers. Yu introduced ShinyAnimalCV, an open-source application that provides a user-friendly interface for performing CV tasks. Yu says CV technology optimizes decision-making through timely and individualized animal care. Affordable two- and three-dimensional camera sensors, combined with various algorithms, have provided opportunities to improve livestock production systems. Yu anticipates ShinyAnimalCV can contribute to CV research and teaching in the animal science community.



Automation and Deep Learning to Advance Phenomics and Postharvest Handling

Charlie Li, a UF/IFAS professor of agricultural and biological engineering, talked about sustainably intensifying agricultural production and food supply while preserving the environment. Li will go over multiple research projects that leverage agricultural robotics and deep learning to address challenges spanning the food chain — from breeding to harvest and postharvest handling. He presented a novel modular agricultural robotic system (MARS) that is an autonomous, multi-purpose, and affordable robotic platform for in-field automated phenotyping and precision farming.

AI and machine learning to reduce postharvest losses

Tie Liu, an assistant professor of horticultural sciences, says the quality of fresh fruits and vegetables deteriorates before reaching consumers due to biochemical processes and compositional changes. In his presentation Liu talked about how he and his team are addressing food waste and loss problems. They’re leveraging imaging-based machine learning technologies to understand postharvest deterioration and microbial spoilage of fresh produce to evaluate the quality. Liu proposes a research program to identify proteins and compounds as “freshness indicators” and to help develop easy-to-use tools to accurately estimate the freshness of produce and or contamination of produce.

From soil mapping to informed decision making for ecosystem health: An envisioned target and the role of AI

After Liu speaks, Nikos Tziolas, an assistant professor of soil, water, and ecosystem sciences at the UF/IFAS Southwest Research and Education Center, talked about how monitoring soil health means we must improve evidence-based conservation strategies. This can be achieved through multidimensional approaches, the use of AI and cost-effective digital tools. Tziolas will present advanced data-handling techniques. These innovations boost surveys and provide essential soil-testing advisory services, showcasing their potential in Florida. His future strategy involves integrating spectra from over 100 countries and developing a user-friendly online prediction tool with localized multi-channel AI models to enhance global predictions.

A new approach to training agricultural robotics through synthetic data and digital twin

Dana Choi, an assistant professor of agricultural and biological engineering at the Gulf Coast Research and Education Center, talked about how AI advancements offer groundbreaking solutions across numerous fields, including agriculture. However, training machine-learning models for agricultural robotics presents significant challenges.
She stressed the scarcity of high-quality training data, complex real-world agricultural environments and the time-consuming, costly nature of physical testing. Choi presented her current research in which she leverages synthetic data and digital twins to train machine-learning algorithms. Learn more about this research here.

Geospatial Artificial Intelligence for Ecosystem Service Quantification

At the same seminar, Chang Zhao, an assistant professor of agronomy, presented how her research can advance quantification and mapping ecosystem services, which include ways that human health and well-being are closely tied to the environment. Those include benefits such as food production, carbon storage and sequestration, habitat conservation, and non-material benefits such as recreation and landscape appreciation. She described several research projects she’s leading or working on, including remote sensing and AI-based methods to quantify and map land-cover change, vegetation dynamics and biodiversity. Zhao’s ultimate goal is to help us understand ecosystem services and develop easy-to-use geographic information tools that inform evidence-based decision-making for sustainable land use planning and management.

The mission of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is to develop knowledge relevant to agricultural, human and natural resources and to make that knowledge available to sustain and enhance the quality of human life. With more than a dozen research facilities, 67 county Extension offices, and award-winning students and faculty in the UF College of Agricultural and Life Sciences, UF/IFAS brings science-based solutions to the state’s agricultural and natural resources industries, and all Florida residents.
