Dictionary of Computer and Internet Terms: drizzle
drizzle
an algorithm to combine digital images while resampling them to a higher resolution, invented by Andrew Fruchter and Richard Hook for processing Hubble Space Telescope data.
The key step, however, is that before this is done, each drop is shrunk so that it does not cover the entire original pixel, but only its central portion. In effect, the drizzle algorithm resamples from spots rather than squares. As a result, the larger pixel size of the original images has less of a degrading effect on the output.
