Feature Based Image Mosaicing using Regions of Interest for Wide Area Surveillance Camera Arrays with Known Camera Ordering
Brett S. Ballard · OhioLink ETD Center (Ohio Library and Information Network) · 2011
Today, modern surveillance systems utilizing camera arrays can capture several square miles of ground activity at high resolution from a single aircraft.A camera array uses multiple cameras to capture images synchronously with partial overlap between cameras' fields of view.This allows a wide area to be monitored continuously in real time by image analysts or processed for information such as object identification and location tracking.The task of combining these images from each individual camera into one large image containing all of the images' views of the scene activity is commonly called image mosaicing in the field of computer vision.Though the process of image mosaicing is not new, what makes image mosaicing a topic of current research is the difficulty and variety of both problems and solutions.The objective of this thesis is to demonstrate the most suitable system to mosaicing images captured by wide area surveillance camera arrays with known camera ordering by using regions of interest combined with a feature based approach.The proposed system utilizes iii algorithms for feature extraction, matching, and estimation.The key difference I would like to express my sincere gratitude to each person who has made my graduate experience possible and full of cherishable memories for the years to come.In particular I would like to thank: • My wife, Chelsea: For supporting me throughout the quest to continue my education and pursue my research interests.Your love and support have given me the strength to persevere against all of life's obstacles and challenges, pressing on to reach my goals.• My son, Oliver: For inspiring me with your pure and wonderful spirit.Both being with you and thinking about you gives me an inner strength which makes accomplishing anything seem possible.• Dr. Eric Balster: For fulfilling the role of graduate and thesis advisor.Your engineering guidance and the time you invested in me helped me to grow both academically and professionally as an engineer.You always keep an active perspective for helping students to achieve greater things.For this I am also personally grateful.•
