Exact cone beam reconstruction for a saddle trajectory

Physics in Medicine and Biology, 2006
We propose an exact shift-invariant filtered backprojection (FBP) algorithm for inversion of cone beam (CB) data in the case where the source trajectory is a saddle. The algorithm allows for axial truncation of the cone beam data. The algorithm involves only one family of filtering lines on the detector plane, and it does not depend on the existence of

Locality-Constrained Sparse Reconstruction for Trajectory Classification

2014 22nd International Conference on Pattern Recognition, 2014
Trajectory classification has been extensively investigated in recent years, however, problems remain when processing incomplete trajectories of noises and local variations. In this paper, we propose a Locality-constrained Sparse Reconstruction (LSR) approach that explores both sparsity and local adaptability for robust trajectory classification.

Visual Trajectory Reconstruction of a CubeSat after Deployment

2015
The paper tackles the problem of estimating accurately the relative state of a CubeSat after in-orbit deployment using a camera. The objective is to provide quick and precise relative orbit information to support the ground operations during this critical phase.
