I'm doing the project for the iOS application. For this project, I'm using OpenCV. Specifically, I added OpenCV_contrib modules to obtain the information of face landmarks.

During applied OpenCV_contrib, I have met one problem. facemark->loadModel("load model"); For detecting the facemark, I have to find the model files.

I wonder that how can I find the model files for "facemark->loadModel("load model"); "
