Foreground Removal In A Multi-Camera System, Daniel T. Mortensen
Foreground Removal In A Multi-Camera System, Daniel T. Mortensen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Traditionally, whiteboards have been used to brainstorm, teach, and convey ideas with others. However distributing whiteboard content remotely can be challenging. To solve this problem, A multi-camera system was developed which can be scaled to broadcast an arbitrarily large writing surface while removing objects not related to the whiteboard content. Related research has been performed previously to combine multiple images together, identify and remove unrelated objects, also referred to as foreground, in a single image and correct for warping differences in camera frames. However, this is the first time anyone has attempted to solve this problem using a multi-camera system. …
Incorporating Spatial Information Into Gas Plume Detection In Hyperspectral Imagery, Cameron S. Grant
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 …
