FirebaseVisionCloudLandmarkDetector

public class FirebaseVisionCloudLandmarkDetector extends Object
implements Closeable

Detector for finding popular natural and man-made structures within an image.

A cloud landmark is created via getVisionCloudLandmarkDetector(FirebaseVisionCloudDetectorOptions) or getVisionCloudLandmarkDetector() if you wish to use the default FirebaseVisionCloudDetectorOptions. For example, the code below creates a cloud landmark detector with default options.


 FirebaseVisionCloudLandmarkDetector cloudLandmarkDetector =
    FirebaseVision.getInstance().getVisionCloudLandmarkDetector();

To find landmark in an image, you first need to create an instance of


      FirebaseVisionImage

from a Bitmap, ByteBuffer, etc. See


      detectInImage(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 landmarks in the supplied FirebaseVisionImage.


 Task<List<FirebaseVisionCloudLandmark>> task =
    cloudLandmarkDetector.detectInImage(image);
 task.addOnSuccessListener(...).addOnFailureListener(...);

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

Detects landmarks from supplied image.

For best efficiency, create a FirebaseVisionImage object using one of the following ways:

fromMediaImage(Image, int) with a JPEG formatted image from android.hardware.camera2.
fromBitmap(android.graphics.Bitmap).

All other


            FirebaseVisionImage

factory methods will work as well, but possibly slightly slower.

Returns

A Task that asynchronously returns the detected List of FirebaseVisionCloudLandmark. The list is empty if nothing is found.
