Smile Detection
This code uses Python's dlib to detect facial landmarks and count the number of times you smile (A little creepy, I know)
Dlib
Dlib is a general purpose cross-platform software library written in the programming language C++. It is an open-source software released under a Boost Software License.
Facial landmarks
Smile count
Libraries Required
Imutils, dlib, numpy, opencv
