Halcon (proprietary notation: HALCON) is a proprietary library of algorithms for image processing and machine vision. The software is developed by the Munich company MVTec.

The Halcon library provides about 2000 different operators and provides interfaces to many cameras and frame grabbers. It is designed for operation on multicore systems and for GPGPU.

Halcon is used predominantly in industrial and medical applications. Similar proprietary libraries include the Cognex Vision Library and the Matrox Imaging Library.

The IDE uses the proprietary HDevelop. Otherwise, there is also an extension for Microsoft Visual Studio.
