Drizzling

• + is photometrically faithful and introduces minimal artifacts
• + produces noise correlations only on small scales and in predictable ways
• + can handle arbitrary geometric distortions
• + can handle pixel weighting in a fully flexible way
• + is relatively fast and efficient for large images
• - requires images with matched PSFs
• - cannot achieve super-resolution
• - produces output images that have a small amount of space-variant smoothing
