Windows

Getting the Dependency

  • Emgu CV use WCF(Windows Communication Foundation) therefore requires .Net 3.0
  • For Version 3.0+, the required vcrt dlls are included in the "x86" and "x64" folder. You will be ready as long as you copy all the unmanaged dlls in the "x86" and "x64" folder to the folder of executable.
  • For version 2.4.x the bundled OpenCV binary is build with Visual Studio 2010, you will needs to installed MSVCRT 9.0 SP1 x86 or MSVCRT 9.0 SP1 x64 to resolve the dependency issue.
  • For Version 2.0 - 2.3, the bundled OpenCV binary is build with Visual Studio 2008, you will needs to installed MSVCRT 9.0 SP1 to resolve the dependency issue.
  • For Version 1.5, the bundled OpenCV pre1.1 binary is build with Visual Studio 2005, you will needs to installed MSVCRT 8.0 SP1 to resolve the dependency issue.

Building the Examples

  • Follow this link to the file server on Source Forge.
  • Download and extract the windows installer.
  • Install the software
  • Go to the "Solution\Windows.Desktop" folder.
  • Open Emgu.CV.Example.sln and build the solution. At this point, you should be able to run the example programs.

Creating a New Project in Visual Studio

To use the framework in Visual Studio, you need to

  • Download and extract the binary files package Emgu.CV.Windows.Binary-{version}.zip

For a Full guide to using the dependencies under Visual Studio and C# see the C# Tutorial.

Core Functionality

Managed Code
  • Create a new Visual Studio project or use an existing one
  • Add reference
    • For 3.1 release. Add the Emgu.CV.World.dll to Reference of the project.
    • For 3.0 release. Add the two files Emgu.Utils.dll and Emgu.CV.dll to References of the project.
  • Optionally put the following lines in the top of your code to include the Emgu.CV namespace.

using Emgu.CV;

using Emgu.CV.Structure;

Open CV unmanaged dll

Copy the "x86" and "x64" folder, along with the DLLs inside those folder to the folder of the executable. Emgu CV is able to load the unmanaged binary from the "x86" folder when running in 32bit mode, and load the unmanaged binary from the "x64" folder when running in 64bit-mode. If you are only targeting the "x64" platform, you only need to copy the "x64" folder.

CUDA (GPU) package
Emgu CV 3.x

Only package containing -cuda in its name (e.g. libemgucv-xxx-cuda-xxx ) has CUDA processing enabled.

  • Adding reference:
    • For 3.1 release. You don't need to add extra references. The Cuda namespace is part of the Emgu.CV.World.dll.
    • For 3.0 release. Add Emgu.CV.Cuda.dll to References
  • Optionally put the following lines in the top of your code to include the Emgu.CV.Cuda namespace.

using Emgu.CV.Cuda;

Emgu CV 2.x

CUDA (GPU) for image processing is only available for Emgu CV rev 2.2.1 and later. Only package containing -gpu in its name (e.g. libemgucv-xxx-gpu-xxx) has CUDA (GPU) processing enabled.

  • Add Emgu.CV.GPU.dll to References
  • Optionally put the following lines in the top of your code to include the Emgu.CV.GPU namespace.

using Emgu.CV.GPU;

Commercial package

The commercial version is build with Intel Compiler, Intel IPP and (commercial version of) Intel TBB. It contains -tbb-ipp-icc in the package file name. Once you purchase the commercial version you will received an email containing the instructions to download these packages.

For commercial release > v2.3.1:

  • Copy the Intel C++ compiler runtime redistributable dlls libiomp5md.dll, libmmd.dll & svml_dispmd.dllto the execution directory
  • Copy the TBB dll file tbb.dll to the execution directory

GUI

To display image using Emgu's ImageBox

  • Add Emgu.CV.UI.dll to References
  • Optionally put the following lines in the top of your code to include the Emgu.CV.UI namespace.

using Emgu.CV.UI;

Machine Learning

  • Adding reference
    • For 3.1 release. You don't need to add extra reference.
    • For release up to and including 3.0 release, add Emgu.CV.ML.dll to References
  • Optionally put the following lines in the top of your code to include the Emgu.CV.ML namespace.

using Emgu.CV.ML;

Start Developing

  • Follow the Tutorial to learn how to use Emgu CV.
  • Hello World (C# or VB .NET) is a good starting point.

The type initializer for 'Emgu.CV.CvInvoke' threw an exception.

If you see this exception, please check the following

Have you installed MSVCRT?

  • For Version 3.0+, the required vcrt dlls are included in the "x86" and "x64" folder. You will be ready as long as you copy all the unmanaged dlls in the "x86" and "x64" folder to the folder of executable.
  • For Version 2.4+, the bundled OpenCV binary is build with Visual Studio 2010, you will needs to installed MSVCRT 10.0 SP1 x86 or MSVCRT 10.0 SP1 x64 to resolve the dependency issue.
  • For Version 2.0+, the bundled OpenCV binary is build with Visual Studio 2008, you will needs to installed MSVCRT 9.0 SP1 to resolve the dependency issue.
  • For Version 1.5, the bundled OpenCV pre1.1 binary is build with Visual Studio 2005, you will needs to installed MSVCRT 8.0 SP1 to resolve the dependency issue.

Have you copied the OpenCV dlls to the execution directory?

  • Make sure the unmanaged DLLs are in the execution directory.
    • For Emgu CV version >=2.4.2, this means the "x86" and "x64" folder and all the dlls within the folders. The folder names and file structures should not be altered when deploying with the application.
    • For EMGU CV version 2.4 cudart64_42_9.dll, cvextern.dll, npp64_42_9.dll, opencv_calib3dXXX.dll, opencv_contribXXX.dll, opencv_coreXXX.dll, opencv_features2dXXX.dll, opencv_flannXXX.dll, opencv_highguiXXX.dll, opencv_imgprocXXX.dll, opencv_legacyXXX.dll, opencv_mlXXX.dll, opencv_nonfreXXX.dll, opencv_objectdetectXXX.dll, opencv_videoXXX.dll,</code?> where <code>XXX is the OpenCV version number.
    • For Emgu CV version 2.2, 2.3 this means the following dlls: opencv_calib3dXXX.dll, opencv_contribXXX.dll, opencv_coreXXX.dll, opencv_features2dXXX.dll, opencv_highguiXXX.dll, opencv_imgprocXXX.dll, opencv_legacyXXX.dll, opencv_mlXXX.dll, opencv_objectdetectXXX.dll, opencv_videoXXX.dll where XXX is the OpenCV version number.
    • For Emgu CV version <= 2.1, this means the following dlls:cvXXX.dll, cvauxXXX.dll, cxcoreXXX.dll, highguiXXX.dll, opencv_ffmpegXXX.dll, mlXXX.dllcvextern.dll where XXX is the OpenCV version number.
  • The best way to set up your project is:
    • Copy the unmanaged DLLs to your project folder
    • Right click on the project, click Add->Existing Item and select all unmanaged DLLs. Add them to the project.
    • For each of the included Dlls, left click on it, find the "Copy to Output Directory" option and select "Copy if newer"

Are you missing any dependency?

Download Dependency Walker and use it to open the "cvextern.dll" file. Check if any dependency is missing.

I have checked all of above but I still got the Exception

In this case, please try to build and run the examples. After building the examples, try to run the "Hello World" Program.

If "Hello World" runs without any problem, compare it with you project, find the difference in configuration and fix it.

If "Hello World" get the same "The type initializer for 'Emgu.CV.CvInvoke' threw an exception." message, try to find out the InnerException and report it to the discussion forum

Building from Git

If you wants to build the development version of Emgu CV from source code, you can to get it from GIT following instructions on This page.

Prerequisite

  • You will need to install CMAKE in-order to build the unmanaged C++ code (OpenCV and cvextern.dll).

OSX

Getting the Dependency

Emgu CV has adapted to use cmake to compile all it source code (as well as OpenCV). Make sure you have cmake installed.

  • Xcode

Make sure you have Xcode and Command Line Tools installed.

Building from Source

  • To build from source, you will need a Git client to check out the source code from SourceForge. For more information, see GIT. The following command can be used to check out the source:
git clone https://github.com/emgucv/emgucv emgucv
  • Go to emgucv directory
cd emgucv
  • It is recommend to check out a branch of emgucv, for example, 2.4.10 instead of the master development code.
git checkout EMGUCV_3_1_R16_12
  • Initialize opencv, tesseract-ocr and cvblob submodules
git submodule update --init --recursive
cd platform/osx
./configure
cd ..

Sit back and wait as this will build OpenCV and Emgu CV

  • Now go to the bin folder
cd bin
  • Try to run the example
mono Example.PlanarSubdivision.monoexe

You should see the planar subdivision window. Note that the first time a mono program is executed, it may take a considerable time to start, some times as long as one minute. Any consecutive execution should be fast.

System.DllNotFoundException

If you encounter this exception during

mono Example.PlanarSubdivision.monoexe
Your OpenCV build might be incomplete (e.g. GTK+ 2.x devel library is missing). To trace the cause of the error, run
