Automatic vehicle trajectory data reconstruction at scale
Transportation Research Part C: Emerging Technologies, 2023 In this paper we propose an automatic trajectory data reconciliation to correct common errors in vision-based vehicle trajectory data. Given "raw" vehicle detection and tracking information from automatic video processing algorithms, we propose a pipeline including (a) an online data association algorithm to match fragments that describe the same ...

Trajectory fusion for three-dimensional volume reconstruction [PDF]
Computer Vision and Image Understanding, 2008 We address the 3D volume reconstruction problem from depth adjacent sub-volumes acquired by a confocal laser scanning microscope (CLSM). Our goal is to align the sub-volumes by estimating a set of optimal global transformations that preserve morphological continuity of medical structures, e.g., blood vessels, in the reconstructed 3D volume. We approach

The Big Picture: An Improved Method for Mapping Shipping Activities
Remote Sensing, 2023 Density maps support a bird’s eye view of vessel traffic, through providing an overview of vessel behavior, either at a regional or global scale in a given timeframe. However, any inaccuracies in the underlying data, due to sensor noise or other factors,

Rosette Trajectories for Fast MRI Based on an Adaptive Reconstruction Method
IEEE Access, 2021 Non-Cartesian MRI k-space trajectories provide faster and more motion-robust data acquisitions than those of Cartesian trajectories. In this paper, we focus on the rosette trajectory and generalize the weighted rosette trajectories for fast undersampled ...

Feasibility of spiral fMRI based on an LTI gradient model
NeuroImage, 2021 Spiral imaging is very well suited for functional MRI, however its use has been limited by the fact that artifacts caused by gradient imperfections and B0 inhomogeneity are more difficult to correct compared to EPI. Effective correction requires accurate

CT Scanning Imaging Method Based on a Spherical Trajectory. [PDF]
PLoS ONE, 2016 In industrial computed tomography (CT), the mismatch between the X-ray energy and the effective thickness makes it difficult to ensure the integrity of projection data using the traditional scanning model, because of the limitations of the object's ...
