Running AI models on iOS, Android and Windows using Xamarin

I created a NuGet package a while ago to allow you to run models exported from the Azure Custom Vision service on iOS and Android in Xamarin apps from your cross-platform code. You can read about this here. Since then, the Custom Vision service has added ONNX export, meaning you can now run these models on-device on Windows as well. This meant it…

Running custom vision models on a Windows device

Recently I wrote about creating AI models using the Azure Custom Vision Service. In these posts I looked at creating and training models, running them online, then finally exporting the models to run on iOS using CoreML and Android using TensorFlow. Recently Microsoft announced another way to export models - as ONNX models that can be run using Win…

Describing a photo in a mobile app using Azure Computer Vision

I recently gave an introduction to Xamarin talk at Imperial College, London and wanted to build a cool app to show off what you can do on mobile using the awesome Cognitive Services available on Azure. I only had about 30-40 minutes to not only introduce Xamarin, but build an app so I decided to throw together a simple app to take a photo and descr…

Xamarin Essentials

TL;DR - check out Xamarin Essentials in the official documentation. Like a lot of developers, I love how Xamarin allows me to share business logic between iOS and Android apps, and share UI using Forms, but still have access to the native APIs. But one thing has been missing - a consistent, out of the box way of accessing native APIs from cross-pla…

Building mobile apps in F# using Xamarin.Forms and Elmish

FSharp and Xamarin Xamarin is well known for allowing you to build mobile apps in C#, but you can use F# as well. F# is fully supported by the compiler and toolchains in both Visual Studio 2017 and Visual Studio for Mac. It's also pretty much supported by all the Xamarin tools including Xamarin.Forms (except for one bug that should be fixed soon).…

Face identification with Azure FaceAPI

Recently I've been playing with a lot AI and seeing how it can be used in mobile apps to enhance the experience offered to the user. Currently I am playing with facial recognition using the Azure Cognitive Services FaceAPI. This is a stupidly powerful API that can do a LOT of different things: Detect faces in images Analyze those faces to detect ch…

Identifying my daughters toys using AI - Part 5, Plugin for on-device models

In the first part of this series I used the Azure Custom Vision service to create an image classifier to allow me to easily identify my daughters cuddly toys. Once created I tested it by uploading an image and seeing what tags the classifier found for the image. In the second part I accessed this model from a Xamarin app, so that I could use the ca…

Identifying my daughters toys using AI - Part 4, using the models offline on Android

In the first part of this series I used the Azure Custom Vision service to create an image classifier to allow me to easily identify my daughters cuddly toys.

In the first part of this post I used the Azure Custom Vision service to create an image classifier to allow me to easily identify my daughters cuddly toys. Once created I tested it by uploading an image and seeing what tags the classifier found for the image. Although this works, it's a long winded way of using the model. Ideally I'd want it in a…

Getting a users Facebook profile after Authenticating your Xamarin app with Azure

I've recently been looking at the authentication offered by Azure for use in a mobile app, specifically using social auth providers like Facebook to allow a user to sign up for my app. The auth setup is incredibly easy, with Azure taking care of a lot of the hard stuff. There are also loads of great docs on how to get it set up - including the Micr…

Creating Visual Studio project and solution templates - Part 3, VS for Mac extension

In the first part of this set of posts I looked at creating a dotnet new project template, and in the second part I showed how you could easily add this to a Visual Studio for Windows extension. Lets now look at adding it to a Visual Studio for Mac extension, so that our template is available everywhere. It's really easy to create extensions for VS…

Creating Visual Studio project and solution templates - Part 2, VS for Windows extension

In the first part of this set of posts I looked at creating a dotnet new project template. These are great if you like the cli, but if, like me, you'd rather be able to do File->New then dotnet new is not much use. Instead you need a Visual Studio extension that provides a new project or solution type to the IDE. The good news is that you can easil…
