Image recognition and text to speech

There are two TensorFlow Raspberry Pi example apps (https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/pi_examples) located in tensorflow/contrib/pi_examples: label_image and camera. We'll modify the camera example app to integrate text to speech so the app can speak out its recognized images when moving around. Before we build and test the two apps, we need to install some libraries and download the prebuilt TensorFlow Inception model file:

sudo apt-get install -y libjpeg-dev
sudo apt-get install libv4l-dev

curl https://storage.googleapis.com/download.tensorflow.org/models/inception_dec_2015_stripped.zip -o /tmp/inception_dec_2015_stripped.zip

cd ~/tensorflow-1.6.0
unzip /tmp/inception_dec_2015_stripped.zip -d tensorflow/contrib/pi_examples/label_image/data/

To build the label_image and camera apps, run:

make -f tensorflow/contrib/pi_examples/label_image/Makefile
make -f tensorflow/contrib/pi_examples/camera/Makefile
