Analysis of Optimization Methods in Multisteerable Filter Design
Get PDFThe purpose of this thesis is to study and investigate a practical and efficient implementation of corner orientation detection using multisteerable filters. First, practical theory involved in applying multisteerable filters for corner orientation estimation is presented. Methods to improve the efficiency with which multisteerable corner filters are applied to images are investigated and presented. Prior research in this area presented an optimization equation for determining the best match of corner orientations in images; however, little research has been done on optimization techniques to solve this equation. Optimization techniques to find the maximum response of a similarity function to determine how similar a corner feature is to a multioriented corner template are also explored and compared in this research
Lessons for a Young Critic: Immersing Yourself in the Generosity of Henry James toward Balzac
Get PDFAlan D. Weidemann
Get PDFDr. Weidemann is an adjunct faculty member at University of Southern Mississippi, Department of Marine Science, as well as a researcher at the Naval Research Laboratory. His areas of specialization are optical oceanography, propagation of ultraviolet, visible and near-IR electromagnetic radiant energy in oceanic environments, and relationship between inherent and apparent optical properties. Present research is measurement of optical properties on unmanned gliders and development of a flow cytometer to function on the unmanned glid
Wandering Sagebrush
Get PDFWandering Sagebrush is a collection of eight unified short stories. The main themes of the thesis include: the struggle of identity and how one finds the people and places to call family and home. The stories focus on family we make, family we lose, family we choose, and the decisions one makes in the name of family
A Machine Learning Approach to Determine Oyster Vessel Behavior
Get PDFA support vector machine (SVM) classifier was designed to replace a previous classifier which predicted oyster vessel behavior in the public oyster grounds of Louisiana. The SVM classifier predicts vessel behavior (docked, poling, fishing, or traveling) based on each vessel’s speed and either net speed or movement angle. The data from these vessels was recorded by a Vessel Monitoring System (VMS), and stored in a PostgreSQL database. The SVM classifier was written in Python, using the scikit-learn library, and was trained by using predictions from the previous classifier. Several validation and parameter optimization techniques were used to improve the SVM classifier’s accuracy. The previous classifier could classify about 93% of points from July 2013 to August 2014, but the SVM classifier can classify about 99.7% of those points. This new classifier can easily be expanded with additional features to further improve its predictive capabilities
Ion Clustering in Aqueous Salt Solutions Near the Liquid/Vapor Interface
Get PDFMolecular dynamics simulations of aqueous NaCl, KCl, NaI, and KI solutions are used to study the effects of salts on the properties of the liquid/vapor interface. The simulations use the models which include both charge transfer and polarization effects. Pairing and the formation of larger ion clusters occurs both in the bulk and surface region, with a decreased tendency to form larger clusters near the interface. An analysis of the roughness of the surface reveals that the chloride salts, which have less tendency to be near the surface, have a roughness that is less than pure water, while the iodide salts, which have a greater surface affinity, have a larger roughness. This suggests that ions away from the surface and ions near the surface affect the interface in opposite ways

Get PDFI Ching: Wounding Light
No full textBased on the Chinese classic “I Ching,” specifically the Hexagram 36 section, Wounding Light: Hexagram 36 is an appropriation of the section\u27s described strategy to hide one’s abilities from others. The image of light, yang, is hiding behind the dominate yin’s darkness. This classic text is a meditation on the consistency of change. Therefore, I chose to include images of the 5th century BC Western Zhou’s bronze Spade Money, or “bu,” in the four corners of the square. These spades are in a molten state and giving way to the modern Chinese coin now used in I Ching divination. This coin is itself showing decomposition and the visual effects of change. I used an encaustic style of painting for Wounding Light: Hexagram 36 because it’s first known use coincides with the time frame of the “I Ching’s” creation in 5th century BC. “Encaustic” means to burn in and thematically ties into the idea of “Ming I,” the Chinese title for Hexagram 36. “Ming I” roughly translates as a light source hiding, being injured, or eclipsed. Within my title, I endowed the light with purposeful duality. “Wounding Light” can be translated as both light\u27s ability to receive injury and to inflict it. Once wax and pigment are mixed and painted onto panel, they must be torched with fire into place. This process causes the painting to move as it melts and one must adapt to its unpredictable ebbs and flow in order to create success
