OpenCV for Unity is an Assets Plugin for using OpenCV from within Unity.
Since this package is a clone of OpenCV Java, you are able to use the same API as
OpenCV Java 3.4.1(git: opencv,opencv-contrib).
You can image processing in real-time by using the WebCamTexture capabilities of
Unity. (real-time face detection works smoothly on iPhone 5)
Provides a method to interconversion of Unity's Texture2D and OpenCV's Mat.
IDisposable is implemented in many classes.You can manage the resources with
the “using” statement.
PlayMakerActions for OpenCVforUnity is available.
