opencvsharp: a cross-platform .NET wrapper for OpenCV providing comprehensive computer vision and image processing functionality

What it solves

OpenCvSharp provides a way for .NET developers to use OpenCV, a powerful computer vision and image processing library originally written in C/C++, without having to write native code themselves.

How it works

It acts as a cross-platform .NET wrapper around the native OpenCV C/C++ API. It maps the native functionality to .NET classes and methods, allowing developers to perform complex image processing tasks using C#. It includes a ResourcesTracker class to help manage the memory of unmanaged native resources (like Mat objects) to prevent memory leaks.

Who it’s for

It is designed for .NET developers (using .NET 8+, .NET Standard, or .NET Framework) who need to integrate computer vision, image analysis, or image processing capabilities into their applications across Windows, Linux, and macOS.

Highlights

• Cross-Platform Support: Works on Windows (x64 and ARM64), Linux (x64 and ARM64), macOS (Intel and Apple Silicon), and WebAssembly.
• Native API Style: Modeled closely after the original OpenCV C/C++ API for familiarity.
• Flexible Programming: Supports both object-oriented styles and direct native-style function calls.
• Integration: Provides built-in functions to convert OpenCV Mat objects to GDI+ Bitmap or WPF WriteableBitmap.
• Slim Profiles: Offers "slim" runtime packages that exclude GUI and DNN modules to reduce dependency size for headless or containerized environments.
