3D tracking via body radio reflections
… presents WiTrack, a system that tracks the 3D motion of a user from the radio signals reflected off her body. It works even if the person is occluded from the WiTrack device or in a different room. WiTrack does not require the user to carry any wireless device, yet its accuracy exceeds …

Management and Analysis of Localization Information in Uncrewed Aerial Systems
… sidelink mechanisms that enable identification, 3D tracking, command-and-control, and integration with UAS Traffic Management systems, while also identifying key gaps and opportunities for future enhancements in UAV communication and localization. Second, we design and experimentally validate the …

Robust Video Object Tracking via Camera Self-calibration
In this dissertation, a framework for 3D scene reconstruction based on robust video object tracking assisted by camera self-calibration is proposed, which includes several algorithmic components. (1) An algorithm for joint camera self-calibration and automatic radial distortion correction based on …

Effects of Echolocation Calls on the Interactions of Bat Pairs using Transfer Entropy Analysis
Many animal species, including many species of bats, exhibit collective behavior where groups of individuals coordinate their motion. Most bats are unique among these animals in that they use the active sensing mechanism of echolocation as their primary means of navigation. Due to their use of …
