1. Setup Detector @BrittBarak
Local or cloud? @BrittBarak
@BrittBarak
Local •Realtime •Offline support •Security / Privacy •Bandwith •… @BrittBarak
Cloud •More accuracy & features •But more latency •Pricing @BrittBarak
1. Setup Detector @BrittBarak
Text Detector textDetector = FirebaseVision.getInstance() @BrittBarak
Text Detector textDetector = FirebaseVision.getInstance() .onDeviceTextRecognizer @BrittBarak
Text Detector textDetector = FirebaseVision.getInstance() .cloudTextRecognizer @BrittBarak
2. Process input @BrittBarak
FirebaseVisionImage •Bitmap •image Uri •Media Image •byteArray •byteBuffer @BrittBarak
image = FirebaseVisionImage.fromBitmap(bitmap) @BrittBarak Text Detector
3. Execute the model @BrittBarak
Text Detector textDetector.processImage(image) @BrittBarak
Text Detector textDetector.processImage(image) .addOnSuccessListener { } @BrittBarak
Text Detector textDetector.processImage(image) .addOnSuccessListener { firebaseVisionTexts -> processOutput(fbVisionTexts) } @BrittBarak
4. Process output @BrittBarak
firebaseVisionTexts.text @BrittBarak
someTextView.text = firebaseVisionTexts.text @BrittBarak UI

1. Setup Detector @BrittBarak
Image Classifier imageDetector = FirebaseVision.getInstance() @BrittBarak
Image Classifier imageDetector = FirebaseVision.getInstance() .visionLabelDetector @BrittBarak
Image Classifier imageDetector = FirebaseVision.getInstance .visionCloudLabelDetector @BrittBarak
2. Process input @BrittBarak
image = FirebaseVisionImage.fromBitmap(bitmap) @BrittBarak Image Classifier
3. Execute the model @BrittBarak
Image Classifier imageDetector.detectInImage(image) @BrittBarak
Image Classifier imageDetector.detectInImage(image) .addOnSuccessListener{ } @BrittBarak
Image Classifier imageDetector.detectInImage(image) .addOnSuccessListener{ fBLabels -> processOutput(fBLabels) } @BrittBarak
4. Process output @BrittBarak
