+    The face detector we use is made using the classic Histogram of Oriented
     Gradients (HOG) feature combined with a linear classifier, an image pyramid,
     and sliding window detection scheme.  The pose estimator was created by
     using dlib's implementation of the paper:
-        One Millisecond Face Alignment with an Ensemble of Regression Trees by
-        Vahid Kazemi and Josephine Sullivan, CVPR 2014

     Also, note that you can train your own models using dlib's machine learning
     tools.  See train_shape_predictor_ex.cpp to see an example.
