Overview  »

The Wolfram Language not only includes highly optimized implementations of standard image processing filters, but also uses its general symbolic architecture to allow arbitrarily sophisticated filtering and neighborhood processing strategies to be set up using the full mathematical and algorithmic power of the Wolfram Language.
