Predictive Centroiding for Single and Multiple FOVs Star Trackers [PDF]
, 2020 Star centroiding, locating the star image center in a CCD image, is a fundamental process for any star tracker. In this paper, the approximate location of the stars in successive image frames are predicted using the angular velocity as provided by the ...

Hardware Accelerator for Star Centroiding
, 2020 Since the dawn of civilization mankind has gazed upon the night sky and looked for directions. In this modern age, the stars have proved to be a reliable reference point for navigation in space. From small-satellites for gathering weather data to inter-planetary missions like Cassini Orbiter, figuring out the location of a spacecraft has been done ...

Automatic centroid extraction method for noisy star image
IET Image Processing, 2018 Star images obtained by star sensors have a low signal‐to‐noise ratio due to various physical constraints. Low resolution also causes stellar centroid extraction error when traditional methods such as the Gaussian filter or adaptive median filter are utilised to de‐noise star images. An automatic centroid extraction method for noisy low‐resolution star

Remote SensingStar trackers commonly suffer from star point trailing during stellar imaging under dynamic observation conditions. Traditional non-blind deconvolution methods rely on a known Point Spread Function (PSF), whereas blind deconvolution approaches are ...

Interdisciplinary Medicine, EarlyView.Integrated multi‐omics reveals that CD36‐mediated lipid overload in PBMCs drives T cell exhaustion via sub‐lethal ferroptotic stress and AKT suppression. This systemic metabolic signature serves as a robust predictor of immunotherapy response in HCC, suggesting that modulating lipid metabolism can rescue immune fitness.

Limnology and Oceanography: Methods, EarlyView.Abstract Accurate length data underpin many ecological and physiological analyses, from assessing population size structure to parameterizing biomass and bioenergetic models. Stereo‐baited remote underwater video systems (stereo‐BRUVs) provide a non‐intrusive means of collecting these data in situ, supporting management and conservation of motile ...
