The FaceGraphic instance is created when a Face is detected the first time, updated as the face changes, and hidden when the face goes out of the frame. Public override void OnMissing(Detector.Detections detections) Public override void OnUpdate(Detector.Detections detections, item) Public override void OnNewItem(int id, item) Public GraphicFaceTracker(GraphicOverlay overlay) In the above code, a new instance of GraphicFaceTracker is created for every detected face, and each of it builds a face box graphic object over the video stream using the GraphicOverlay view passed in the constructor.īelow is the implementation of the GraphicFaceTracker Return new GraphicFaceTracker(mGraphicOverlay, mCameraSource) In this example, IFactory is implemented within the MainActivity, that has the Create(): MultiProcessor requires an implementation of IFactory to callback when a human Face is detected in the camera. Detect FacesĮvery image frame received from the camera source may contain multiple faces, and each face corresponds to a distinct face identity which is represented by the Tracker created by the multiprocessor. It will ensure the camera resources are used only when the user is using the app. The ideal place to call the StartCameraSource() is in the OnResume() of the Activity, while the OnPause() should stop the preview. Log.Error(TAG, "Unable to start camera source.", e) MPreview.Start(mCameraSource, mGraphicOverlay) check that the device has play services available. GraphicOverlay instance is also passed in so that the face border can be drawn at the time detection. Now that we have access to the camera and the CameraSource is already built, we can start the preview on a custom SurfaceView in this case CameraSourcePreview. In the above code, a MultiProcessor is used to receive detection results and CameraSource.Builder instantiates a camera source with a specified Preview Size, Camera Facing, and required fps. MCameraSource = new CameraSource.Builder(context, detector) Log.Warn(TAG, "Face detector dependencies are not yet available.") The detector will automatically become operational once the library isOperational() can be used to check if the required native library is currently completed, then the above call will not detect any faces. completes before the app is run for the first time.

download a native library to the device in order to do detection. Note: The first time that an app using face API is installed on a device, GMS will SetClassificationType(ClassificationType.All) In this example, we use the default face detector settings and associate a processor to it.įaceDetector detector = new FaceDetector.Builder(context) The FaceDetector.Builder instantiates the FaceDetector with the specified properties. Log.Warn(TAG, "Camera permission is not granted. If (Activit圜ompat.CheckSelfPermission(this, ) = Permission.Granted)

To access the camera on Android, you need to request the user’s permission and add the camera feature to your Android manifest: For this example, I’ll be using the Face APIs to detect human faces from the live camera stream within the app. Google’s Mobile Vision provides a set of APIs for “Detecting Face”, “Recognizing Text”, and “Scanning Barcodes”.

In this post, you’ll learn how to display a camera within the Android app, add face tracking using Google’s Mobile Vision APIs and recognize the person in front of the camera using Microsoft Cognitive Services’ Face API. With services like the Microsoft Cognitive Services API, you can quickly analyze and process your photos by adding just few lines of code. Whether you’re building a consumer app that provides fun filters or an enterprise app that recognizes receipts, adding intelligent tires like these gives you an edge over others. Social media apps today have this intelligence baked in, so you don't have to open another app to make your selfies look extraordinary before you share them with friends and family. While numerous apps in the app store let you do many things with the camera, there are others that do clever manipulation of your images in real time, such as adding a custom mask to your face, manipulating your face to look older or younger, and more.

Whether it's adding filters to your image or letting you adjust focus and exposures manually, apps can essentially transform you into a professional photographer. Camera apps today can do so much more than just take perfect photos.
