Comparative Analysis of Image-shift Measurement Algorithms for Solar
Solar images are obtained by capturing photons emitted by the Sun, and photons interact with the image sensor in a random manner, resulting in photon noise (Jiao et al. 2021). Photon noise is typically the dominant source of noise in solar images due to its larger magnitude compared to other sources.
