Comparison of Dim Star Detection Algorithms for Star Trackers
2023<p>In the following study, the dim star detection performance of a baseline detection algorithm with no image processing was compared to a one-dimensional dilation-based top hat algorithm and a two-dimensional white top hat algorithm which utilized two different structuring elements.

Detecting rising stars in dynamic collaborative networks
Journal of Informetrics, 2017Abstract In today's complex academic environment the process of performance evaluation of scholars is becoming increasingly difficult. Evaluation committees often need to search in several repositories in order to deliver their evaluation summary report for an individual. However, it is extremely difficult to infer performance indicators that pertain

When sunlight is spread out into its different colors or wavelengths, it is cut by several dark gaps. They were first noticed by the English astronomer William Hyde Wollaston (1766–1828) in 1802 (Wollaston 1802), and then investigated in greater detail by the When sunlight is spread out into its different colors or wavelengths, it is cut by several ...

Detection of the very hot central star in NGC2440
Nature, 1986It has been argued1 that the extremely faint central stars of some planetary nebulae must be very hot, with most of their energy output in the ultraviolet. We now report the detection of the central star of the planetary nebula NGC2440 in a narrow-band continuum image using a CCD (charge-coupled device) camera at the prime focus of the Anglo-Australian

Star Detection Algorithm for Estcube-2 Star Tracker
2016Attitude determination is a very important aspect in the mission of spacecraft. There are various methods of determining the attitude of a spacecraft, including, but not limited to, magnetometers, beacons and gyroscopes.[1] Star Trackers are systems consisting of one or multiple image sensors connected to a processing unit.
