ObjectDetection
Stay organized with collections
Save and categorize content based on your preferences.
Entry point to get an ObjectDetector
for finding DetectedObjects
in a supplied image.
An ObjectDetector
is created via
getClient(ObjectDetectorOptionsBase).
Example:
ObjectDetector objectDetector = ObjectDetection.getClient(options);
To perform object 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 objects in the supplied InputImage.
Task<List<DetectedObject>> task = objectDetector.process(image);
task.addOnSuccessListener(...).addOnFailureListener(...);
