FirebaseVision

public class FirebaseVision extends Object

Entry class for Firebase machine learning vision services.

To use this class, get an instance via getInstance() or getInstance(FirebaseApp), and then get an instance of a detector. The code below is an example of getting an instance of a face detector:


 FirebaseVisionFaceDetector faceDetector = FirebaseVision.getInstance().getVisionFaceDetector();
 

See individual detector classes for details.

Gets a FirebaseVisionCloudLandmarkDetector that can detect landmark in a supplied image with default options.

Returns

public FirebaseVisionCloudLandmarkDetector getVisionCloudLandmarkDetector (FirebaseVisionCloudDetectorOptions options)

Gets a FirebaseVisionCloudLandmarkDetector that can detect landmark in a supplied image.

Parameters
options the options for the cloud landmark detector.
Returns

public FirebaseVisionFaceDetector getVisionFaceDetector ()

Gets a FirebaseVisionFaceDetector that detects faces in a supplied image with a default FirebaseVisionFaceDetectorOptions.

Returns

public FirebaseVisionFaceDetector getVisionFaceDetector (FirebaseVisionFaceDetectorOptions options)

Gets a FirebaseVisionFaceDetector that detects faces in a supplied image.

Parameters
options the options for the face detector.
Returns

public FirebaseVisionLabelDetector getVisionLabelDetector ()

Gets a FirebaseVisionLabelDetector that labels a supplied image with a default FirebaseVisionLabelDetectorOptions.

Returns

public FirebaseVisionLabelDetector getVisionLabelDetector (FirebaseVisionLabelDetectorOptions options)

Gets a FirebaseVisionLabelDetector that labels a supplied image.

Parameters
options the options for the image label detector.
Returns

public boolean isStatsCollectionEnabled ()

Determines whether stats collection in FirebaseVision is enabled or disabled

Returns
  • true if stats collection is enabled and false otherwise.

public void setStatsCollectionEnabled (boolean enable)

Enables stats collection in ML Kit vision. The stats include API calls counts, errors, API call durations, options, etc. No personally identifiable information is logged.

The setting is per FirebaseApp, and it is persistent together with app's private data. It means if the user uninstalls the app or clears all app data, the setting will be erased. The best practice is to set the flag in each initialization.

By default the logging is enabled. You have to specifically set it to false to disable logging.
