Facial Detection Test using face_recognition

face_detection.py

# The image you will detect faces in must be named 'test.jpg' and
# must reside in the same directory where you placed this script.
#
# Resulting image, where the detected faces are drawn a white rectangle
# over, is saved in the same directory where you placed this script and
# has the file name, 'result.jpeg'.
