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"); "
I don't know how did you install your OpenCV. But to find the
dataof OpenCV, just go toopencv-master/dataif you downloaded, of go to https://github.com/opencv/opencv/tree/master/data to download.Here is the file list for OpenCV 3.3:
