Microsoft Cognitive Services enables you build apps with powerful algorithms using just a few lines of code via their new API’s. Some of the new additions are that powerful that you start thinking “How does a machine know this?” and have been refined using years of Big Data and machine learning. For example, you can pass up an image to an API and return a description of the photo, face detection and emotion recognition. The same services can be applied to videos too, from face tracking, stabilization and motion detection.

Please watch the video below which I seen at Microsoft Build Conference, it outlines an excellent use case for the services.

Most of the API’s have a playground area where you can test out the API straight from the web page. Go on, give them a try.
