OpenCV wrapper for .NET
What it solves
OpenCvSharp provides a way for .NET developers to use the powerful OpenCV library for image processing and computer vision without needing to write C++ code. It acts as a cross-platform wrapper that brings OpenCV's extensive functionality to the .NET ecosystem.
How it works
It functions as a .NET wrapper around the native OpenCV C/C++ API. The library is designed to mimic the native API style as closely as possible, allowing developers to use native-style functions or an object-oriented approach. It manages unsafe native resources via the IDisposable interface and uses a managed expression tree (MatExpr) for arithmetic operations to prevent memory leaks during chained calculations.
Who it’s for
.NET developers building applications that require computer vision, image manipulation, or image analysis on Windows, Linux, macOS, or in the browser via WebAssembly.
Highlights
- Cross-Platform Support: Works across Windows (x64/ARM64), Linux (x64/ARM64), macOS (x64/arm64), and WebAssembly.
- Flexible Deployment: Offers different runtime profiles (Full, Headless, and Slim) to reduce dependency footprints, especially for containerized services.
- Native API Fidelity: Closely follows the OpenCV C/C++ API style for ease of transition.
- Integration Extensions: Includes specialized extensions for GDI+, WPF, and Avalonia to simplify image conversion and display.
