#
#  Example from code built on the Flask web framework (and Werkzeug)
#  Accepts uploading a photo file in the 'photo' form member, then
#  copies it into a memory byte array and converts it to a numpy array
#  which in turn can be decoded by OpenCV.
#
#  Beware that this increases the memory pressure and you should 
#  configure a max request size before doing so.
# 
#  It saves a round-trip to a temporary file, though.
