Real-time camera motion tracking in planar view scenarios [PDF]
, 2016 We propose a novel method for real-time camera motion tracking in planar view scenarios. This method relies on the geometry of a tripod, an initial estimation of camera pose for the first video frame and a primitive tracking procedure.

Correlation tracking via robust region proposals
The Journal of Engineering, 2019 Recently, correlation filter-based trackers have received extensive researching interest because of their simplicity and superior running speed. However, such trackers perform poorly when the target undergoes occlusion, viewpoint change, or other ...

Dynamic scheduling of parallel real-time jobs by modelling spare capabilities in heterogeneous clusters [PDF]
, 2003 In this research, a scenario is assumed where periodic real-time jobs are being run on a heterogeneous cluster of computers, and new aperiodic parallel real-time jobs' modelled by Directed Acyclic Graphs (DAG), arrive at the system dynamically.

A Diverse Space Target Dataset With Multidebris and Realistic On-Orbit Environment
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 As the number of space targets increases year by year, space situational awareness plays an important role in satellite security. To keep satellite secure, we use space target monitoring, removal, and avoidance to complete space situational awareness ...

Real-Time Stream Processing in Astronomy [PDF]
, 2020 One of problems with ``Big Data'' is when large quantities of data have to be analyzed fast - (almost) in real time. So far in astronomy those situations were not very common. In the next few years a real time processing will become more relevant and the field should prepare for the advent of new instruments and techniques.

Optimal Data Acquisition and Height Retrieval in Repeat-Track Geosynchronous SAR Interferometry
Remote Sensing, 2015 Geosynchronous synthetic aperture radar (GEO SAR) will move in a high orbit of ~36,000 km with a long integration time of hundreds of seconds. It is obviously impacted by orbital perturbations and the Earth’s rotation, which can give rise to un-parallel ...

Recursion induction for real-time processes
Formal Aspects of Computing, 1993 Abstract The theory of timed Communicating Sequential Processes is a mathematical approach to the design and analysis of timed distributed systems. This paper extends the language of timed CSP to include a general treatment of recursion. A semantics for mutual recursion is introduced, together with a sufficient condition for the necessary ...

Smart noise jamming suppression method based on fast fractional filtering
The Journal of Engineering, 2019 Smart noise jamming based on digital radio frequency memory (DRFM) has both oppressive jamming effect and deceptive jamming effect, and it is difficult to be effectively suppressed by traditional anti-jamming methods.

Mixed-Noise Band Selection for Hyperspectral Images
IEEE Access, 2020 Hyperspectral images (HSIs) with abundant spectral information are generally susceptible to various types of noise, such as Gaussian noise and stripe noise.
