Learning Microsoft Cognitive Services - Second Edition

By: Leif Larsen

Overview of this book

Microsoft has revamped its Project Oxford to launch the all new Cognitive Services platform-a set of 30 APIs to add speech, vision, language, and knowledge capabilities to apps. This book will introduce you to 24 of the APIs released as part of Cognitive Services platform and show you how to leverage their capabilities. More importantly, you'll see how the power of these APIs can be combined to build real-world apps that have cognitive capabilities. The book is split into three sections: computer vision, speech recognition and language processing, and knowledge and search. You will be taken through the vision APIs at first as this is very visual, and not too complex. The next part revolves around speech and language, which are somewhat connected. The last part is about adding real-world intelligence to apps by connecting them to Knowledge and Search APIs. By the end of this book, you will be in a position to understand what Microsoft Cognitive Service can offer and how to use the different APIs.

Preface

Diving into the Video API


The Video API provides advanced algorithms for video processing. Using this API, you can build more personalized and intelligent applications.

There are four main features of this API, which we will look into. They are as follows:

  • Face detection and tracking
  • Motion detection
  • Stabilizing shaky videos
  • Generating intelligent video thumbnails

Note

If you have not already done so, register for an API key for the Video API at https://azure.microsoft.com/en-us/try/cognitive-services/. Click on Get API Key next to the Video API.

Microsoft has created a NuGet package, containing the Video API, which allows us to utilize all the features available. Let us start by creating a new project in Visual Studio, based off our MVVM template.

In the newly created project, add Microsoft.ProjectOxford.Video through the NuGet Package Manager.

As this example project will have a lot of common functionality, we just need one View. The example code provided has added a View, VideoView.xaml, to the...
