Drizzle Integration

Super-resolution technique using sub-pixel shifts

Definition

Drizzle (Variable-Pixel Linear Reconstruction) is an algorithm that can increase effective resolution by leveraging sub-pixel shifts between frames. When atmospheric turbulence shifts the image by fractional pixels, drizzle can reconstruct a higher-resolution output. Originally developed for Hubble Space Telescope data. In planetary imaging, 1.5x-2x drizzle can reveal finer detail if seeing conditions and data quality support it.
