In my android application I need both face detection and ORC function at the same time. Can I implement both on same CameraSource? Is it possible?
Context context = getApplicationContext();
TextRecognizer textRecognizer = new TextRecognizer.Builder(context).build();
textRecognizer.setProcessor(new OcrDetectorProcessor(mGraphicOverlay));
FaceDetector detector = new FaceDetector.Builder(context).setClassificationType(FaceDetector.ALL_CLASSIFICATIONS).build();
detector.setProcessor(new MultiProcessor.Builder<>(new GraphicFaceTrackerFactory()).build());
mCameraSource = new CameraSource.Builder(getApplicationContext(), detector)
.setFacing(CameraSource.CAMERA_FACING_BACK)
.setRequestedPreviewSize(1280, 1024)
.setRequestedFps(15.0f)
.setFlashMode(useFlash ? Camera.Parameters.FLASH_MODE_TORCH : null)
.setFocusMode(autoFocus ? Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE : null)
.build();
In the sample codes they pass only one detector at a time to the CameraSource. textRecognizer
or detector
Update: I have found a way. You can create a MultiDetector
and add both FaceDetector
and TextRecognizer
in to that and pass the MultiDetector object in to CameraSource.Builder
MultiDetector multiDetector = new MultiDetector.Builder()
.add(textRecognizer)
.add(detector)
.build();
The multi-detector will receive a series of frames from the camera source. Each frame is submitted to both detectors.
