#OpenCvSharp Cross platform wrapper of OpenCV for .NET Framework.

OpenCVを.NET Frameworkから利用するための、クロスプラットフォームで動作するラッパーです。

If you have Visual Studio 2012 or later, it is recommended to use NuGet. Search 'opencvsharp' on the NuGet Package Manager.

• x86 package - for 32-bit OS
• x64 package - for 64-bit OS

If you do not use NuGet, get DLL files from the release page.

• OpenCV 2.4.8
• Visual C++ 20xx Redistributable Package
• .NET Framework 2.0 or later / Mono

• OpenCvSharp is modeled on the native OpenCV C/C++ API style as much as possible.
• Many classes of OpenCvSharp implement IDisposable. There is no need to manage unsafe resources.
• OpenCvSharp does not force object-oriented programming style on you. You can also call native-style OpenCV functions.
• OpenCvSharp provides functions for converting from Mat/IplImage into Bitmap(GDI+) or WriteableBitmap(WPF).
• OpenCvSharp can work on Mono. It can run on any platform which Mono supports (e.g. Linux and MacOSX).

• オリジナルのC/C++コードと可能な限り似た記述ができるように設計しています。
• 多くのクラスがIDisposableインターフェイスを実装しているので、ネイティブリソース管理が容易です。
• オブジェクト指向な書き方を強制しません。OpenCVのネイティブの関数をそのままの形式で呼べます。
• GDI+やWPFとの相互利用が可能です。OpenCVのMat/IplImageとGDI+のBitmapやWPFのWriteableBitmapとの変換機能があります。
• Monoに対応しています。LinuxやMacOSX等のクロスプラットフォームで動作します。

This library uses cvBlob to implement blob extraction. cvBlob is under the LGPL, so OpenCvSharp follows the cvBlob licensing.
