|
# This example program shows how to find frontal human faces in an image and
|
|
# estimate their pose. The pose takes the form of 68 landmarks. These are
|
|
# points on the face such as the corners of the mouth, along the eyebrows, on
|
|
# the eyes, and so forth.
|
|
#
|
|
# This face detector 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
|
|
# and was trained on the iBUG 300-W face landmark dataset.
|
|
#
|
|
# Also, note that you can train your own models using dlib's machine learning
|
|
# tools. See train_shape_predictor.py to see an example.
|
|
#
|
|
# You can get the shape_predictor_68_face_landmarks.dat file from:
|
|
# http://dlib.net/files/shape_predictor_68_face_landmarks.dat.bz2

|
# COMPILING/INSTALLING THE DLIB PYTHON INTERFACE
|
|
# You can install dlib using the command:
|
|
# pip install dlib
|
|
#
|
|
# Alternatively, if you want to compile dlib yourself then go into the dlib
|
|
# root folder and run:
|
|
# python setup.py install
|
|
# or
|
|
# python setup.py install --yes USE_AVX_INSTRUCTIONS
|
|
# if you have a CPU that supports AVX instructions, since this makes some
|
|
# things run faster.
|
|
#
|
|
# Compiling dlib should work on any operating system so long as you have
|
|
# CMake and boost-python installed. On Ubuntu, this can be done easily by
|
|
# running the command:
|
|
# sudo apt-get install libboost-python-dev cmake
|
|
#
|
|
# Also note that this example requires scikit-image which can be installed
|
|
# via the command:
|
|
# pip install scikit-image
|
|
# Or downloaded from http://scikit-image.org/download.html.
