ImageLabeling

  • ImageLabeling is the entry point to get an ImageLabeler for finding ImageLabels in a supplied image.

  • An image labeler is created via getClient(ImageLabelerOptionsBase).

  • To perform label detection, you first need to create an instance of InputImage from a Bitmap, ByteBuffer, etc.

  • After creating an InputImage, you can detect labels using imageLabeler.process(image).

  • To release resources, ensure ImageLabeler.close() is called when the ImageLabeler instance is no longer needed.
public class ImageLabeling extends Object

Entry point to get an ImageLabeler for finding ImageLabels in a supplied image.

An image labeler is created via getClient(ImageLabelerOptionsBase).

Example:

 ImageLabeler imageLabeler = ImageLabeling.getClient(options);

To perform label detection in an image, you first need to create an instance of InputImage from a Bitmap, ByteBuffer, etc. See InputImage documentation for more details. For example, the code below creates an InputImage from a Bitmap.

 InputImage image = InputImage.fromBitmap(bitmap, rotationDegrees);

Then the code below can detect labels in the supplied InputImage.

 Task<List<ImageLabel>> task = imageLabeler.process(image);
 task.addOnSuccessListener(...).addOnFailureListener(...);
