3D Trajectory Matching by Pose Normalization Arie Croitoru, Peggy Agouris, and Anthony Stefanidis   View Paper (PDF)   Return to Session 6: Virtual Reality and 3D Abstract Recent technological advances have made it possible to collect large amounts of 3D trajectory data. Such data play an essential role in numerous applications and are becoming increasingly important in mobile computing. One of the fundamental challenges in many of these application areas is the assessment of similarity between trajectories. As objects moving in a 3D space may often exhibit a similar motion pattern but may differ in location, orientation, and scale, the similarity assessment metho ... ©2006 Association for Computing Machinery
