Raw data of the Fourier base-frequency phase-shift algorithm（2025.05）

Aiming at the demand of high accuracy and high real-time of center localization of tiny targets, a sub-pixel localization algorithm based on Fourier fundamental frequency phase shift is proposed, and the performance comparison of this algorithm with other five sub-pixel localization algorithms is analyzed using MATLAB simulation. The dataset contains the comparative results of the six algorithms in terms of localization accuracy, running time, and anti-noise characteristics.
