PULSE-ECHO IMAGE FORMATION USING NONQUADRATIC REGULARIZATION WITH SPECKLE-BASED IMAGES BY

To Kely, my family, and friends. iii ACKNOWLEDGMENTS There are many people to which I would like to thank: my adviser, Professor William O'Brien Jr., for helping me with many useful comments and ideas but also for demanding my best e®ort in everything that I do and helping me to challenge myself every step of the way. Professor Farzad Kamalabadi, who provided very interesting and useful discussions about regularization methods and image processing issues and encouraged me to accomplish the best possible work. It has been a privilege to work with such outstanding researchers. All the people at the Bioacoustics Research Laboratory (BRL), the ¯nest group that I have ever had the pleasure to work with. I thank my friends and family |C¶esar, Maria Luisa, Carmen and Pammela | for being there always for me and caring about me the way that they do. And ¯nally, to my beloved Kely. She is the greatest joy in my life, and her love and support always motivates me to accomplish my goals
