Using Cognitive Services to locate faces in images

Microsoft offers Cognitive Services, which helps developers to leverage AI features in their applications.

In this recipe, you'll learn how to use the Computer Vision API (Cognitive Service) to detect faces within an image. We will be locating faces, capturing their coordinates, and saving them in different areas of Azure Table storage based on gender.

Cognitive Services apply AI algorithms, so they might not always be accurate. The accuracy returned by Cognitive Services is always between 0 and 1, where 1 means 100% accurate. You can always use the accuracy value returned by Cognitive Services and implement your custom requirements based on the accuracy.

Getting ready

To get started, we need to create a Computer Vision API and configure its API keys so that Azure Functions (or any other program) can access it programmatically.

Make sure that you have Azure Storage Explorer installed and configured to access the...
