This is the alpha release of Emgu CV 2.0 build with OpenCV SVN rev 1918, available from Sourceforge. It is a preview of what the final version of Emgu CV 2.0 will be and is not recommended for production environment. The OpenCV Dlls included in this build are compiled with VS2008. You will needs to install MSVCRT 9.0 SP1 for dependency.
- Emgu CV 2.0 requires .NET 3.5.
- The included OpenCV dlls are built with Visual Studio 2008 and requires MSVCRT 9.0 SP1
- A feature rich ImageBox with Pan and Zoom support.
- Added Debugger Visualizer for Image, Matrix MatDN and DenseHistogram for Visual Studio 2005/2008
- Adapt CMake as the build system for Linux, it is also used to build unmanaged code on windows.
- Fixed a marshaling error in MCvBoostParams, MCvDTreeParams and MCvRTParams structures. The following class finally works in 22.214.171.124 release: Boost Tree, Decision Tree and Random Tree.
- Fixed a bug in cvReduce function
- Feature Tree can now be constructed either as Spill-Tree or K-d Tree
- Histogram class is obsolete, it is replaced by DenseHistogram class, which
- is runtime-serializable
- can be calculated from Matrix.
- can be visualized by a Debugger Visualizer
- The following classes are new in v2.0
- ERTrees (Extreme Random Trees)
- The following class are now runtime-serializable
- Improvements to Image class.
- Added _GammaCorrect function
- Added ExtractMSER (Maximally stable extremal regions) function
- Make _EqualizeHist() work for color image as well: For color images, a HSV representation of the image is first obtained and the V (value) channel is histogram equalized.

- Improved performance when retrieving Voroni-facets in PlanarSubdivision class.
- Improved performance for the Rotate function in Image class when crop is false.
