From: Efficient shift-variant image restoration using deformable filtering (Part II): PSF field estimation
Sampled PSFs with pair indexes from the lower right quadrant of BLUR1 PSF field with low level of noise and different star densities. Top left: medium density (40,000 stars) with pooling region of 256×256pixels; top right: high density with smaller pooling region (128×128pixels). In the bottom, both linear plots show a central cross section of selected PSFs for all considered density studied cases.
