The contact frontier in Galactic civilization networks: radial structure and the Galactic habitable zone
Kohji Tsumura
The probability of interstellar contact depends not only on the abundance of technological civilizations but also on their spatial connectivity. Treating civilizations as nodes lin…
Toward Semantic Scene Understanding for Fine-Grained 3D Modeling of Plants
Mohamad Qadri, Harry Freeman, Eric Schneider +1
Agricultural robotics is an active research area due to global population growth and expectations of food and labor shortages. Robots can potentially help with tasks such as prunin…
Autonomous Apple Fruitlet Sizing with Next Best View Planning
Harry Freeman, George Kantor
In this paper, we present a next-best-view planning approach to autonomously size apple fruitlets. State-of-the-art viewpoint planners in agriculture are designed to size large and…
3D Skeletonization of Complex Grapevines for Robotic Pruning
Eric Schneider, Sushanth Jayanth, Abhisesh Silwal +1
Robotic pruning of dormant grapevines is an area of active research in order to promote vine balance and grape quality, but so far robotic efforts have largely focused on planar, s…
Occlusion Reasoning for Skeleton Extraction of Self-Occluded Tree Canopies
Chung Hee Kim, George Kantor
In this work, we present a method to extract the skeleton of a self-occluded tree canopy by estimating the unobserved structures of the tree. A tree skeleton compactly describes th…
Autonomous Apple Fruitlet Sizing and Growth Rate Tracking using Computer Vision
Harry Freeman, Mohamad Qadri, Abhisesh Silwal +4
In this paper, we present a computer vision-based approach to measure the sizes and growth rates of apple fruitlets. Measuring the growth rates of apple fruitlets is important beca…
Unsupervised Statistical Learning for Die Analysis in Ancient Numismatics
Andreas Heinecke, Emanuel Mayer, Abhinav Natarajan +1
Die analysis is an essential numismatic method, and an important tool of ancient economic history. Yet, manual die studies are too labor-intensive to comprehensively study large co…
Semantic Feature Matching for Robust Mapping in Agriculture
Mohamad Qadri, George Kantor
Visual Simultaneous Localization and Mapping (SLAM) systems are an essential component in agricultural robotics that enable autonomous navigation and the construction of accurate 3…
A Robust Illumination-Invariant Camera System for Agricultural Applications
Abhisesh Silwal, Tanvir Parhar, Francisco Yandun +1
Object detection and semantic segmentation are two of the most widely adopted deep learning algorithms in agricultural applications. One of the major sources of variability in imag…
Stereo Visual Inertial LiDAR Simultaneous Localization and Mapping
Weizhao Shao, Srinivasan Vijayarangan, Cong Li +1
Simultaneous Localization and Mapping (SLAM) is a fundamental task to mobile and aerial robotics. LiDAR based systems have proven to be superior compared to vision based systems du…
Active Learning with Gaussian Processes for High Throughput Phenotyping
Sumit Kumar, Wenhao Luo, George Kantor +1
A looming question that must be solved before robotic plant phenotyping capabilities can have significant impact to crop improvement programs is scalability. High Throughput Phenot…
Learning End-to-end Multimodal Sensor Policies for Autonomous Navigation
Guan-Horng Liu, Avinash Siravuru, Sai Prabhakar +2
Multisensory polices are known to enhance both state estimation and target tracking. However, in the space of end-to-end sensorimotor control, this multi-sensor outlook has receive…
