The Wolfram Language provides broad and deep built-in support for both programmatic and interactive modern industrial-strength image processing—fully integrated with the Wolfram Language's powerful mathematical and algorithmic capabilities. The Wolfram Language's unique symbolic architecture and notebook paradigm allow images in visual form to be included and manipulated directly, both interactively and in programs.
