# OpenCvSharp [](https://ci.appveyor.com/project/shimat/opencvsharp/branch/master) [](https://github.com/shimat/opencvsharp/blob/master/LICENSE) Cross platform wrapper of OpenCV for .NET Framework. Old versions of OpenCvSharp are maintained in [opencvsharp_2410](https://github.com/shimat/opencvsharp_2410). ## Installation ### NuGet | Package | Description | Link | |---------|-------------|------| |**OpenCvSharp4**| OpenCvSharp core libraries | [](https://badge.fury.io/nu/OpenCvSharp4) | |**OpenCvSharp4.Windows**| All-in-one package for Windows - same as [OpenCvSharp3-AnyCPU](https://www.nuget.org/packages/OpenCvSharp3-AnyCPU/) | [](https://badge.fury.io/nu/OpenCvSharp4.Windows) | |**OpenCvSharp4.runtime.win**| Native bindings for Windows x64/x86 | [](https://badge.fury.io/nu/OpenCvSharp4.runtime.win) | |**OpenCvSharp4.runtime.ubuntu.18.04-x64**| Native bindings for Ubuntu 18.04 x64 | [](https://badge.fury.io/nu/OpenCvSharp4.runtime.ubuntu.18.04-x64) | |(beta packages)| Development Build Package | https://ci.appveyor.com/nuget/opencvsharp | Native binding (OpenCvSharpExtern.dll / libOpenCvSharpExtern.so) is required to work OpenCvSharp. To use OpenCvSharp, you should add both `OpenCvSharp4` and `OpenCvSharp4.runtime.*` packages to your project. Currently, native bindings for Windows and Ubuntu 18.04 are released. Packages named OpenCvSharp3-* and OpenCvSharp-* are deprecated. - [OpenCvSharp3-AnyCPU](https://www.nuget.org/packages/OpenCvSharp3-AnyCPU/) - [OpenCvSharp3-WithoutDll](https://www.nuget.org/packages/OpenCvSharp3-WithoutDll/) - [OpenCvSharp-AnyCPU](https://www.nuget.org/packages/OpenCvSharp-AnyCPU/) - [OpenCvSharp-WithoutDll](https://www.nuget.org/packages/OpenCvSharp-WithoutDll/) ### Windows Add `OpenCvSharp4` and `OpenCvSharp4.runtime.win` NuGet packages to your project. You can use `OpenCvSharp4.Windows` instead. ### Ubuntu 18.04 Add `OpenCvSharp4` and `OpenCvSharp4.runtime.ubuntu.18.04.x64` NuGet packages to your project ``` dotnet new console -n ConsoleApp01 cd ConsoleApp01 dotnet add package OpenCvSharp4 dotnet add package OpenCvSharp4.runtime.ubuntu.18.04-x64 # -- edit Program.cs --- # dotnet run ``` ### Downloads If you do not use NuGet, get DLL files from the [release page](https://github.com/shimat/opencvsharp/releases). ## Requirements * [OpenCV 4.0.1](http://opencv.org/) with [opencv_contrib](https://github.com/opencv/opencv_contrib) * (Windows)[Visual C++ 2017 Redistributable Package](https://go.microsoft.com/fwlink/?LinkId=746572) * [.NET Framework 2.0](http://www.microsoft.com/ja-jp/download/details.aspx?id=1639) or later / [.NET Core 2.0](https://www.microsoft.com/net/download) / [Mono](http://www.mono-project.com/Main_Page) OpenCvSharp may not work on UWP and Unity platform. Please consider using [OpenCV for Unity](https://www.assetstore.unity3d.com/en/#!/content/21088) ## Documents https://shimat.github.io/opencvsharp_docs/index.html ## Usage For more details, see **[samples](https://github.com/shimat/opencvsharp_samples/)** and **[Wiki](https://github.com/shimat/opencvsharp/wiki)** pages. ```C# // Edge detection by Canny algorithm using OpenCvSharp; class Program { static void Main() { Mat src = new Mat("lenna.png", ImreadModes.Grayscale);        // Mat src = Cv2.ImRead("lenna.png", ImreadModes.Grayscale);        Mat dst = new Mat(); Cv2.Canny(src, dst, 50, 200); using (new Window("src image", src)) using (new Window("dst image", dst)) { Cv2.WaitKey(); } } } ``` ## Features * 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](http://www.mono-project.com/Main_Page). It can run on any platform which [Mono](http://www.mono-project.com/Main_Page) supports (e.g. Linux). ## OpenCvSharp Build Instructions ### Windows - Install Visual Studio 2017 or later - VC++ features are required. - Get all submodules ``` git submodule update --init --recursive ``` - Build OpenCvSharp - Open `OpenCvSharp.sln` and build ### Ubuntu 18.04 - Build OpenCV with opencv_contrib. - https://www.learnopencv.com/install-opencv-4-on-ubuntu-18-04/ - Install .NET Core SDK. https://dotnet.microsoft.com/download/linux-package-manager/ubuntu18-04/sdk-2.1.202 - Get OpenCvSharp source files ``` git clone https://github.com/shimat/opencvsharp.git cd opencvsharp git fetch --all --tags --prune && git checkout ${OPENCVSHARP_VERSION} ``` - Build native wrapper `OpenCvSharpExtern` ``` cd opencvsharp/src mkdir build cd build cmake -D CMAKE_INSTALL_PREFIX=${YOUR_OPENCV_INSTALL_PATH} .. make -j make install ``` You should add reference to `opencvsharp/src/build/OpenCvSharpExtern/libOpenCvSharpExtern.so` ``` export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/home/shimat/opencvsharp/src/build/OpenCvSharpExtern" ``` - Add `OpenCvSharp4` NuGet package to your project ``` dotnet new console -n ConsoleApp01 cd ConsoleApp01 dotnet add package OpenCvSharp4 # -- edit Program.cs --- # dotnet run ``` ### Older Ubuntu Refer to the [Dockerfile](https://github.com/shimat/opencvsharp/blob/master/Dockerfile) and [Wiki pages](https://github.com/shimat/opencvsharp/wiki). ## License Licensed under the [BSD 3-Clause License](https://github.com/shimat/opencvsharp/blob/master/LICENSE). ## Donations If you find the OpenCvSharp library useful and would like to show your gratitude by donating, here are some donation options.
