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 ...

Surface Vessel Tracking in Airborne Infrared Imagery [PDF]
2019 27th Signal Processing and Communications Applications Conference (SIU), 2019 Visual target tracking has been studied for decades and still remains a challenging problem. Ship tracking on infrared images has numerous challenges compared to conventional target tracking such as fast changing of appearance. Rapid appearance change caused by the manoeuvring movement of the target of image acquiring platform, confusion and occlusion ...

Vessel Axis Tracking Using Topology Constrained Surface Evolution [PDF]
IEEE Transactions on Medical Imaging, 2007 An approach to 3-D vessel axis tracking based on surface evolution is presented. The main idea is to guide the evolution of the surface by analyzing its skeleton topology during evolution, and imposing shape constraints on the topology. For example, the intermediate topology can be processed such that it represents a single vessel segment, a ...

Retinal Vessels Segmentation Techniques and Algorithms: A Survey
Applied Sciences, 2018 Retinal vessels identification and localization aim to separate the different retinal vasculature structure tissues, either wide or narrow ones, from the fundus image background and other retinal anatomical structures such as optic disc, macula, and ...

Exponential ε-tracking and ε-stabilization of second-order nonholonomic SE(2) vehicles using dynamic state feedback [PDF]
, 2002 In this paper, we address the problem of ε-tracking and ε-stabilization for a class of SE(2) vehicles with second-order nonholonomic constraints. We introduce a class of transformations called near-identity diffeomorphism that allow dynamic partial ...

Vessel Tracking System Based LoRa SX1278
Jurnal Ilmiah Teknik Elektro Komputer dan Informatika, 2023 This research presents a vessel tracking system that provides real-time coordinate and speed information. The idea behind the development of this system originated from Automatic Identification System (AIS) technology, which functions as a vessel monitoring system in maritime areas.
