This folder needs to contain the landmark predictor data file for the examples using ofxFaceTracker2 to work, and it needs to contain the image-net-2012 weights and class names for examples with ofxCcv to work.
Run sh setup.sh
from the root folder to download the shape_predictor_68_face_landmarks.dat
data file automatically from sourceforge.net/projects/dclib/files/dlib/v18.10/shape_predictor_68_face_landmarks.dat.bz2, as well as image-net-2012.sqlite3 and image-net-2012.words.
Alternatively, download those files manually and unzip the landmarks file.
