![]() ![]() To make this, we would need to write PInvoke of OpenCV methods, which are many, which means a lot of time. Therefore, it's suggested that you use as few calling as you can.Ģ - Using a Wrapper of OpenCV C++: with this way, we'll use C++ Shared Libraries (.so) and call its methods from C# ( ). It's also worth saying that this way, we have three layers of programming languages (C# - Java - C++), so we have performance losses with method calling (JNI is a burden). There's also a NuGet of a fork of this project: that can simplify the installation and use, but I didn't use this so I can't say if it works.Īs this method is a Binding of OpenCV4Android and not pure OpenCV, you'll use the documentation of OpenCV4Android ( ). If you want to use a newer version, you can download a newer version of OpenCV4Android (file with name opencv-version-android-sdk.zip in OpenCV SourceForge, Ex: OpenCV4Android 4.1.0 on link ) and replace the content of folder "/src/OpenCV.Binding/Jars" in the previous project with the content of folders "/sdk/native/libs" and "/sdk/native/3rdparty/libs" of an extracted OpenCV4Android. dll size" to generate a dll and reference it, or you can insert in your Visual Studio Solution the Visual Studio Project of folder "/src/OpenCV.Binding" and add a Reference from your project to this new project. You can follow the installation instructions and "Reducing the. ![]() It was implemented in, where it was used OpenCV 3.1.0. With the binding, we have an interface between Java and C# (More information in ). There is more than one way to use OpenCV on Xamarin.Android:ġ - Using a Binding of OpenCV4Android: OpenCV4Android is a wrapper of OpenCV (C++) for Android (Java) using JNI. ![]()
