Review:
Point Spread Function (psf) Estimation
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Point Spread Function (PSF) estimation is a fundamental process in optical imaging and microscopy used to characterize the response of an imaging system to a point source. Accurate PSF estimation enables improved image deblurring, super-resolution, and quantitative analysis by modeling how light propagates through the system. It is essential in various fields including astronomy, biomedical imaging, and computational photography, where understanding the system's resolution limit and distortions is crucial.
