opencvsharp

Building from source requires multiple tools like CMake, vcpkg, and Visual Studio, with intricate steps for different platforms, as outlined in the build instructions, which can be a barrier for custom integrations or debugging.

Does not support Unity or Xamarin, and CUDA features are absent, restricting its use in game development or GPU-accelerated applications without significant extra work, as admitted in the README.

Despite IDisposable, developers must diligently use 'using' statements or ResourcesTracker to avoid memory leaks, adding cognitive load and potential for errors in complex code, which the README warns about with examples.

Relies on native binaries (OpenCvSharpExtern.dll/.so) which must be correctly deployed and matched, complicating distribution and increasing the risk of runtime issues on target systems, especially with platform-specific packages.
