## What it is
Emgu CV is a cross-platform .NET wrapper for the OpenCV image processing library, allowing OpenCV functions to be called from .NET-compatible languages like C# and VB.NET. It runs on Windows, Linux, macOS, iOS, and Android, and can be compiled with Visual Studio, Unity, and the dotnet CLI.

## Use cases
- process images from a C# application using OpenCV
- build a cross-platform computer vision app in .NET
- detect faces or objects in a MAUI mobile app
- run OpenCV functions from VB.NET or F#
- use OpenCV in a Unity game or simulation
- perform GPU-accelerated image processing with CUDA in .NET
- classify or recognize images in a .NET application

## When to choose
- you develop in C# or another .NET language and need OpenCV functionality
- you need one vision library that targets desktop and mobile platforms
- you want NuGet-based installation with optional CUDA support
- you are building Unity or MAUI apps that need image processing

## When to avoid
- you work primarily in Python or C++ and can use OpenCV directly
- you need a fully permissive license for commercial use without checking terms
- you need the very latest OpenCV features on day one
- your project is not on the .NET ecosystem

## Facets
- artifact type: library
