FirebaseVisionLabelDetector

public class FirebaseVisionLabelDetector extends Object
implements Closeable Closeable

Detector for finding FirebaseVisionLabels in a supplied image.

A label detector is created via getVisionLabelDetector(FirebaseVisionLabelDetectorOptions), or getVisionLabelDetector() if you wish to use the default options. For example, the code below creates a label detector with default options.

 FirebaseVisionLabelDetector labelDetector =
    FirebaseVision.getInstance().getVisionLabelDetector();
To perform label detection in an image, you first need to create an instance of FirebaseVisionImage from a Bitmap, ByteBuffer, etc. See FirebaseVisionImage documentation for more details. For example, the code below creates a FirebaseVisionImage from a Bitmap. 
      FirebaseVisionImage image = FirebaseVisionImage.fromBitmap(bitmap);
Then the code below can detect labels in the supplied FirebaseVisionImage. 

 Task<List<FirebaseVisionLabel>> task = labelDetector.detectInImage(image);
 task.addOnSuccessListener(...).addOnFailureListener(...);

public Task<List<FirebaseVisionLabel>> detectInImage (FirebaseVisionImage image)

Detects image labels from supplied image.

For best efficiency, create a FirebaseVisionImage object from fromBitmap(android.graphics.Bitmap). All other FirebaseVisionImage factory methods will work as well, but possibly slightly slower.
