Intelligent Mobile Projects with TensorFlow

Overview of this book

As a developer, you always need to keep an eye out and be ready for what will be trending soon, while also focusing on what's trending currently. So, what's better than learning about the integration of the best of both worlds, the present and the future? Artificial Intelligence (AI) is widely regarded as the next big thing after mobile, and Google's TensorFlow is the leading open source machine learning framework, the hottest branch of AI. This book covers more than 10 complete iOS, Android, and Raspberry Pi apps powered by TensorFlow and built from scratch, running all kinds of cool TensorFlow models offline on-device: from computer vision, speech and language processing to generative adversarial networks and AlphaZero-like deep reinforcement learning. You’ll learn how to use or retrain existing TensorFlow models, build your own models, and develop intelligent mobile apps running those TensorFlow models. You'll learn how to quickly build such apps with step-by-step tutorials and how to avoid many pitfalls in the process with lots of hard-earned troubleshooting tips.

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...
