I couldn't have completed this program of study without the support and sacrifice of my husband, Michael. His help was above and beyond the call of duty and no one could have a more loyal spouse than I. He probably will never know how much I appreciate all of the extra work he did for me, all while having to put his full effort into his own stress-filled job. I also appreciate the time he took to provide feedback on this work.
I also want to thank the Opportunity Plan, Incorporated, of Canyon, Texas, and in particular Cathryn Wright, who provided me with a generous academic scholarship. This assistance proves that no matter how long someone has been away from home, she is still remembered.
I finally want to recognize the hard work done by Michael Villafana and Thu Hang Tran in the preparation of the image data bases used in this project. Their efforts proved invaluable, especially with several short-notice requests for new images.
This work was supported by the Office of Naval Research under contract N00014-K-0613. I would also like to acknowledge the support of the San Antonio Area Foundataion.
