Basic face tracking sample

Shows how to use the FaceTracker class to find human faces within an video stream.

Note: This sample is part of a large collection of UWP feature samples. If you are unfamiliar with Git and GitHub, you can download the entire collection as a ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

Specifically, this sample shows how to:

• Initialize and manage the FaceTracker object
• Start a live webcam capture and display the video stream
• Execute face tracking to find human faces within the video stream
• Acquire video frames from the video capture stream and convert it to a format supported by FaceTracker
• Retrieve results from FaceTracker and visualize them

Note The Windows universal samples require Visual Studio 2017 to build and Windows 10 to execute.

To obtain information about Windows 10 development, go to the Windows Dev Center

To obtain information about Microsoft Visual Studio and the tools for developing Windows apps, go to Visual Studio

The FaceTracker is intended to operate on a running video stream and is optimized to find and track human faces in real-time. In order to detect human faces within a static image or a single video frame, use the FaceDetector API instead.
