Camera face detection sample
Provides an end-to-end sample to show how to write a camera application using the Windows.Media.Capture API in conjunction with orientation sensors to cover the functions that most camera apps will require. In addition, it will show a simple way to use the Face Detection effect included in Windows. This sample is based on the Basic camera app sample.
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:
- Manage the MediaCapture object throughout the lifecycle of the app and through navigation events.
- Acquire a camera located on a specific side of the device. In this case, the sample attempts to get the front camera.
- Start and stop the preview to a UI element, including mirroring for front-facing cameras.
- Take a regular picture to a file, taking into account the orientation of the device.
- Handle rotation events for both, the device moving in space and the page orientation changing on the screen. Also apply any necessary corrections to the preview stream rotation.
- Handle MediaCapture Failed event to clean up the MediaCapture instance when an error occurs.
- Manage the Face Detection effect, including creation, configuration, activation/deactivation, registering for events, and cleanup.
- Render face bounding boxes as an overlay on the camera preview, taking mirroring and rotation into account.
This sample also implements a custom UI to better simulate the experience that a camera application would provide, so any messages intended for the developer are printed to the debug console.
Client: Windows 10
Server: Windows Server 2016 Technical Preview
Phone: Windows 10
Build the sample
- If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
- Start Microsoft Visual Studio 2017 and select File > Open > Project/Solution.
- Press Ctrl+Shift+B, or select Build > Build Solution.
Run the sample
The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.
Deploying the sample:
- Select Build > Deploy Solution.
Deploying and running the sample:
- To debug the sample and then run it, press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or select Debug > Start Without Debugging.
