FirebaseVisionLabelDetector

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(...);
