摘要

本文介绍了一种天文图像配准算法。该算法使用原始图像行和列的均值进行配准，并通过比较图像之间的不同偏移量，找到与最大相似度相对应的最佳偏移量。相似度是通过商的标准偏差除以均值来评估的。本文还讨论了该算法的理论可行性。通过实际测试，证实了该算法的快速性和鲁棒性。

A fast photometric image alignment algorithm with row and column means

This paper introduces an astronomical image alignment algorithm. This algorithm uses the means of the rows and columns of the original image for alignment, and finds the optimal offset corresponding to the maximum similarity by comparing different offsets between images. The similarity is evaluated by the standard deviation of the quotient divided by the means. This paper also discusses the theoretical feasibility of this algorithm. Through practical testing, it has been confirmed that the algorithm is fast and robust.
