There are many services that allow using AI inside mobile applications via REST APIs but at a cost of time as the results get processed and returned back to the application. Lucky for us, we are upon a new future where we can leverage the power of Mobile Applications and Artificial Intelligence locally and offline! I will walkthrough how I built a native Android app in C# using Xamarin and then used the Azure Custom Vision Service to train my data set and create a TensorFlow classifier model which I embedded directly into the mobile app. Azure Custom Vision optimizes the models for the constraints of a mobile device which allows real time image classification! The ability to do this locally and offline on a device has many interesting use cases, like a DIY security home camera, enterprise applications in locations with limited or low network , your very own HotDog-NotHotDog app and much more!
