[[Emgu CV]] is written entirely in C#. The benefit is that it can be [[Compiling_with_Monodevelop|compiled in Mono]] and therefore is able to run on any platform Mono supports, including iOS, Android, Windows Phone, Mac OS X and Linux. A lot of efforts has been spent to have a pure C# implementation since the headers have to be ported, compared with managed C++ implementation where header files can simply be included. But it is well worth it if you see [[Compiling_with_Monodevelop|Emgu CV running on Fedora 10]]! Plus it always gives you the comfort knowing that your code is cross-platform.

Advantage of Emgu CV

Cross Platform

Emgu CV is written entirely in C#. It can be run on any platform .net supports, including iOS, Android, Mac OS, Linux and windows. A lot of efforts has been spent to have a pure C# implementation since the headers have to be ported, compared with managed C++ implementation where header files can simply be included. But it is well worth it if you see Emgu CV running on Fedora 10! Plus it always gives you the comfort knowing that your code is cross-platform.

Cross Language and comes with example code

Emgu CV can be used from several different languages, including C#, VB.NET, C++ and IronPython. On this wiki, we provide examples for all those languages, which are available from the Examples section on Tutorial page. Our Discussion Forum is also available if you have any questions related to your favourite programming language.
