Incorporating Spatial Information Into Gas Plume Detection In Hyperspectral Imagery, Cameron S. Grant
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Detection of chemical plumes in hyperspectral data is a problem having solutions that focus on spectral information. These solutions neglect the presence of the spatial information in the scene. The spatial information is exploited in this work by assignment of prior probabilities to neighborhood configurations of signal presence or absence. These probabilities are leveraged in a total probability approach to testing for signal presence in a pixel of interest. The two new algorithms developed are named spatial information detection enhancement (SIDE) and bolt-on SIDE (B-SIDE). The results are explored in comparison to the clutter matched filter (CMF), a standard spectral …
Cooperative Remote Sensing And Actuation Using Networked Unmanned Vehicles, Haiyang Chao
Cooperative Remote Sensing And Actuation Using Networked Unmanned Vehicles, Haiyang Chao
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This dissertation focuses on how to design and employ networked unmanned vehicles for remote sensing and distributed control purposes in the current information-rich world. The target scenarios are environmental or agricultural applications such as river/reservoir surveillance, wind profiling measurement, and monitoring/control of chemical leaks, etc. AggieAir, a small and low-cost unmanned aircraft system, is designed based on the remote sensing requirements from environmental monitoring missions. The state estimation problem and the advanced lateral flight controller design problem are further attacked focusing on the small unmanned aerial vehicle (UAV) platform. Then the UAV-based remote sensing problem is focused with further flight …
