Batch Continuous-Time Trajectory Estimation
… localization (and control). Although motion-estimation techniques utilizing passive cameras have been a core topic in robotic research for decades, we note that this technology is unable to produce reliable results in low-light conditions (which account for roughly half the day). For this …

Probabilistic models for mobile phone trajectory estimation
… with the problem of determining the track or trajectory of a mobile device - for example, a sequence of road segments on an outdoor map, or a sequence of rooms visited inside a building - in an energy-efficient and accurate manner. GPS, the dominant positioning technology today, has two major …

Multi-view tracking of soccer players with dynamic cameras
… the information from the soccer field for camera trajectory estimation and background modeling. Tracking is first carried out independently for each camera view with a layered tracker. Then we integrate the results of layered trackers from multiple views through MCMC inference over tracklet-to- …

Energy Efficient Target Tracking in Wireless Sensor Networks: Sleep Scheduling, Particle Filtering, and Constrained Flooding
… forms and shapes, such as idle listening, trajectory estimation, and data propagation. In this dissertation, we study three correlated problems on energy efficient target tracking in WSNs: sleep scheduling, particle filtering, and constrained flooding. We develop a Target Prediction and …

On-orbit inspection of a rotating object using a moving observer
… inspector may have similar time constants, the trajectory of the inspector must be estimated to disambiguate the motion of the target from that of the inspector. The algorithms presented in this thesis require that the inspector satellite be equipped with a star tracker, an inertial measurement …

Autonomous Fire Suppression Using Feedback Control for Robotic Firefighting
… of water leaks and sprays, real-time trajectory estimation, and a feedback controller for error correction in longer-range firefighting. The close proximity suppression algorithm uses IR fire detection IR stereo processing to localize a fire. Feedback of the fire size and fire target …

A Low-cost autonomous tracking camera system for 3d marker-less motion capture of animals in the wild
… was used to extract 2D key-points, and then a trajectory optimisation-based 3D pose estimation method called Full Trajectory Estimation (FTE) was used to reconstruct the 3D trajectories of the subject. Quantitative and qualitative experimental results are provided to validate the systems …

Real-time brain-machine interface architectures : neural decoding from plan to movement
… on either estimating the continuous movement trajectory or target intent. However, natural movement often incorporates both. Moreover, both target and trajectory information are encoded in the motor cortical areas. These suggest that BMIs should be designed to combine these principal aspects …

Graphical SLAM for urban UAV navigation
… footprint data of the existing region, for UAV trajectory estimation and environment mapping. Our approach consists of three main aspects: graphical modeling, map-based processing, and inference. First, we use a probabilistic graph, specifically a directed acyclic graph, to model the trajectory …

AM-FM methods for image and video processing
… formulation for the instantaneous frequency (IF) estimation: a variable spacing, local quadratic phase method (VS-LQP) is presented. VS-LQP produces much more accurate results than current AM-FM methods. At significant noise levels (SNR < 30dB), for single component images, the VS-LQP method …
