Marine Vessel Tracking using a Monocular Camera [PDF]
Proceedings of the 2nd International Conference on Deep Learning Theory and Applications, 2021 In this paper, a new technique for camera calibration using only GPS data is presented. A new way of tracking objects that move on a plane in a video is achieved by using the location and size of the bounding box to estimate the distance, achieving an average prediction error of 5.55m per 100m distance from the camera.

Comparing spatial patterns of marine vessels between vessel-tracking data and satellite imagery
Frontiers in Marine Science, 2023 Monitoring marine use is essential to effective management but is extremely challenging, particularly where capacity and resources are limited. To overcome these limitations, satellite imagery has emerged as a promising tool for monitoring marine vessel ...

A Deep Learning Streaming Methodology for Trajectory Classification
ISPRS International Journal of Geo-Information, 2021 Due to the vast amount of available tracking sensors in recent years, high-frequency and high-volume streams of data are generated every day. The maritime domain is no different as all larger vessels are obliged to be equipped with a vessel tracking ...

Vessel tree tracking in angiographic sequences [PDF]
Journal of Medical Imaging, 2017 We present a method to track vessels in angiography [contrast filled vessels in two-dimensional (2-D) x-ray fluoroscopy]. Finding correspondence of a vessel tree from consecutive angiogram frames provides significant value in computer-aided clinical applications such as fast vessel tree segmentation, three-dimensional (3-D) vessel topology ...

Video-rate 3D Particle Tracking with Extended Depth-of-field in Thick Biological Samples [PDF]
, 2017 We present a single-aperture 3D particle localisation and tracking technique with a vastly increased depth-of-field without compromising optical resolution and throughput. Flow measurements in a FEP capillary and a zebrafish blood vessel are demonstrated
