IntroductionNow it became easier to use OpenCV on C#.
In this tip, I propose a simple method to get EmguCV* (OpenCV) running in a .NET application, using a NuGet package called myEmguCV.Net.
This is a NuGet package that makes it easy to start an application with EmguCV.
* This version uses EmguCV wrapper for x86 version of OpenCV.
BackgroundIt was often difficult to use OpenCV in C#, although you can download EmguCV, and follow the steps listed on EmguCV website, it was not the simplest task.
I have created a NuGet package containing all DLLs from EmguCV and OpenCV, so all you need to do is: on Visual Studio Express, add this Package to your Solution, add some sample code, and Run.
Overview of the Steps
- Just create a new Visual Studio Express solution
- Add the NuGet package myEmguCV.Net
- Add sample code
- Press F5 (Run)
Installing the NuGet Package
- Right click the References
- Select Manage NuGet packages
- Search for myEmguCV.Net
- Click Install
- Wait for download and installation to finish
Writing CodeAfter adding the myEmguCV.Net package, you can run some code for Computer Vision tasks:
For example, something like this:
// Sample Image<Hsv, byte> bitmap = new Image<Hsv, byte>(@"C:\temp\LicensePlate.bmp"); Hsv lowerLimit = new Hsv(0, 0, 200); Hsv upperLimit = new Hsv(5, 255, 255); var imageHSVDest = bitmap.InRange(lowerLimit, upperLimit); CvInvoke.cvShowImage("imageHSVDest", imageHSVDest); CvInvoke.cvWaitKey(0);Now press F5 and then there should be a Window.

Points of InterestThis is a complete package containing binary DLLs, about 131MB.
Includes binaries of: OpenCV, EmguCV for .NET, x86 version
One requirement is to have installed MSVCRT 9.0 SP1 x86
