An overview of different APIs
Now that you have seen a basic example of how to detect faces, it is time to learn a bit about what else Cognitive Services can do for you. When using Cognitive Services, you have 21 different APIs to hand. These are, in turn, separated into five top-level domains depending on what they do. These domains are vision, speech, language, knowledge, and search. We will learn more about them in the following sections.
APIs under the vision flags allow your apps to understand images and video content. They allow you to retrieve information about faces, feelings, and other visual content. You can stabilize videos and recognize celebrities. You can read text in images and generate thumbnails from videos and images.
