Centroid Extraction Method Based on Multi-Scale Gaussian Fitting and Subpixel Edge Reconstruction
Accurate spot-centroid localization is fundamental for determining optical metrics such as modulation transfer function (MTF) and effective focal length (EFL). Conventional methods struggle under non-ideal conditions—asymmetric spots, high noise, and vibration—and mid-wave infrared (MWIR) vibration...
