Ever since the Microsoft Cognitive Services were available, I always wanted to give those APIs a spin. The power of machine learning at your fingertips, that’s pretty awesome! Today I managed to hook up a Xamarin app to the Computer Vision API to do some image recognition. The basic idea of this app is really simple: Let the Computer Vision tell you what you’re looking at. Simply take a picture, pass it along the Computer Vision API and display the result in the app. It’ll tell you what it thinks you’re looking at.
Because this is a simple demo, we’ll be using Xamarin.Forms. Although I’ll only focus on iOS here, you can easily extend it to Android and/or UWP. The source code can be found on Github.
So let’s see how you’re able to use the Computer Vision API inside your Xamarin app. I’ll give you a small hint: it’s really simple!
