Title: Global Shipping Container Monitoring Using Machine Learning with Multi-Sensor Hubs and Catadioptric Imaging
 
Abstract: We describe a framework for global shipping container monitoring using machine learning with multi-sensor hubs and infrared catadioptric imaging. A wireless mesh radio satellite tag architecture provides connectivity anywhere in the world which is a significant improvement to legacy methods. We discuss the design and testing of a low-cost long-wave infrared catadioptric imaging device and multi-sensor hub combination as an intelligent edge computing system that, when equipped with physics-based machine learning algorithms, can interpret the scene inside a shipping container to make efficient use of expensive communications bandwidth. The histogram of oriented gradients and T-channel (HOG+) feature as introduced for human detection on low-resolution infrared catadioptric images is shown to be effective for various mirror shapes designed to give wide volume coverage with controlled distortion. Initial results for through-metal communication with ultrasonic guided waves show promise using the Dynamic Wavelet Fingerprint Technique (DWFT) to identify Lamb waves in a complicated ultrasonic signal.
 
Bio: Victor E. Trujillo II, from Questa, New Mexico, earned a B.S. in Operations Research from the United States Military Academy (USMA) at West Point in 2000, and was commissioned as an Engineer Officer in the U.S. Army.  He served assignments with 4th Infantry Division at Fort Hood, Texas and 20th Engineer Brigade at Fort Bragg, North Carolina before returning to graduate school.  He earned a M.S. in Mathematics and Statistics from Georgetown University in 2010 with a follow-on assignment to the Department of Mathematical Sciences at USMA.  As an Instructor/Assistant Professor for three years he taught courses in Differential and Integral Calculus and served as an academic representative to the Army Football Team.  He then served in the 1st Infantry Division at Fort Riley, Kansas and NATO Rapid Deployable Corps in Istanbul, Turkey.  Victor started his Ph.D. program at William & Mary in 2016 under the direction of Dr. Mark Hinders.  His research interests are machine learning and edge computing.  He is married to Elizabeth Mason and they have one son, Victor III.
