An adaptive parameter optimization method for astronomical image alignment using Bayesian optimization. I. A hierarchical search strategy for FWHM and SNR
Yongjie Zhang, Yigong Zhang, Zhenjun Zhang +6
The alignment and stacking of astronomical images are fundamental steps for detecting faint objects and performing high?precision astrometry. In traditional alignment workflows, th…
Astrometric observations of a near-Earth object using the image fusion technique
Yigong Zhang, Jiancheng Wang, Jie Su +2
The precise astrometric observation of small near-Earth objects (NEOs) is an important observational research topic in the astrometric discipline, which greatly promotes multidisci…
A fast point-pattern matching algorithm based on statistical method
Zhen-Jun Zhang, Yi-Gong Zhang, Xiang-Ming Cheng +2
We propose a new pattern-matching algorithm for matching CCD images to a stellar catalogue based statistical method in this paper. The method of constructing star pairs can greatly…
