OpenCvSharp is a cross-platform .NET wrapper for the OpenCV computer vision library, published as NuGet packages with bundled native binaries. Its API closely mirrors the native OpenCV C++ API while using C# conventions like typed enums, exceptions, and deterministic disposal.

Use cases

• use OpenCV from C# or .NET applications
• process and transform images in ASP.NET Core
• detect features and match keypoints in .NET
• build image processing pipelines in C#
• read and write video files from .NET
• run computer vision in the browser via Blazor WebAssembly
• port existing OpenCV C++ or Python code to .NET

When to choose

• you need OpenCV functionality in a .NET application
• you want an API that maps closely to native OpenCV so C++/Python examples translate easily
• you need cross-platform support including Windows, Linux, macOS, and WebAssembly
• you want native binaries delivered via NuGet without manual builds

When to avoid

• you are using Python, C++, or Java, where native OpenCV bindings are more direct
• you need .NET Framework support and prefer the actively developed OpenCvSharp5 line (use OpenCvSharp4 instead)
• you need GPU/CUDA modules that may not be included in the packaged native binaries
