The use of vision and audition in stealth applications is well recognized; however, other perceptual senses can also play a valuable role. This report discusses the sense of smell (olfaction), its use in nature and everyday life, and its potential applications in military and stealth operations. The sense of smell has largely been overlooked and underutilized in warfare, being restricted to crowd control and deterrent applications. However, the olfactory dimension can be a promising addition to other Department of Defense applications, such as stealth operations, deception, misdirection, and...

The Defense Advanced Research Projects Agency's (DARPA) Mind's Eye Project seeks to generate research in computer vision and artificial intelligence. The goal of the project is to create computer systems capable of perceiving humans in action and describe the actions in conversational English. This book documents efforts to create ground truth labeling for video files that can be used as training data for computer systems, as well as efforts to organize these data into a well-structured database. Ground-truth labeling efforts include data gathered through panel studies as well as...

In March 2012, an international team of scientists, engineers, and technicians gathered at the southwest border of the United States with specialized equipment to collect data on people, animals, and vehicles traveling in the rugged terrain. The goal of the effort is to collect data in the natural environment and develop robust algorithms to detect people, animals, and vehicles with fewer false alarms and high confidence. The Canadian team used SASNet; the Israeli team used Pearls of Wisdom; University of Memphis brought a Profiling sensor; and the University of Mississippi, Night Vision and...
