}- 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).
