The ImageProcessing package is a new Mathematica 4 add-on package for digital image processing. Designed for speed and functionality, the package features a comprehensive collection of over one hundred one- and two-dimensional linear and non-linear image operators for common measurement, analysis and image enhancement tasks. Here we give a quick tour, with references to the full documentation in the User's Guide, of selected ImageProcessing functions and operators. All the examples are taken from the User's Guide.
