Smile Detection with a Deep Convolutional Neural Net using Keras.
This example is based on the mnist_cnn.py example, running at 32x32 instead of 28x28.
To compile the ZMQVideoInput app, openFrameworks is required.
If you want to run the realtime capture with OpenCV and you're using OS X, I recommend using Python via Anaconda and installing OpenCV with:
conda install -c https://conda.anaconda.org/menpo opencv3
