Figure 7From: Efficient shift-variant image restoration using deformable filtering (Part II): PSF field estimationSampled PSFs with pair indexes from the lower right quadrant of BLUR1 PSF field with medium star density (40,000 stars, pooling region of 256×256 pixels with half block overlapping). Top left: Original PSFs; top right: estimated PSFs in a 12-bit image (medium noise level). In the bottom, both linear plots show a central cross section of selected PSFs for all considered noise levels.Back to article page
