Synthesizing Realistic Data for Vision Based Drone-to-Drone Detection
In the thesis, we aimed at building a robust UAV(drone) detection algorithm through which, one drone could detect another drone in flight. Though this was a straight forward object detection problem, the biggest challenge we faced for drone detection is the limited amount of drone images for …

Diversifying crop systems by developing intercropping breeding strategies for improving forage yield and quality in oat-legume mixtures
… species and genotype combinations. While UAV-based high-throughput phenotyping is well established in monocrops, few studies examine its application in intercropping field experiments. As detailed in chapter 3, we tested the utility of UAV-derived multispectral vegetation indices (VIs) for …

Influence of Altitude and Scan Angle on UAS-LiDAR Ground Height Measurement Accuracy in Juncus roemerianus Scheele (Black Needle Rush)-dominated Marshes
<p>Coastal marshes are influenced by complex interactions among environmental and human factors. Marsh plant communities exist across subtle elevation gradients which are highly influenced by the local tidal regime. To better understand these dynamic conditions, improved methodologies for acquiring …
