Detection

  • The SDK receives data from a motion sensor and pauses scanning when a device is moving. Turn on/off the video capture motion control:
DocumentReader.Instance().functionality().edit().setVideoCaptureMotionControl(true).apply();

DocumentReader.Instance().functionality().edit().setVideoCaptureMotionControl(true).apply()
  • Pause scanning while a camera is focusing (may decrease the camera processing speed):
DocumentReader.Instance().functionality().edit().setSkipFocusingFrames(true).apply();

DocumentReader.Instance().functionality().edit().setSkipFocusingFrames(true).apply()
  • To omit the document focus check, enable the following parameter:
DocumentReader.Instance().processParams().disableFocusingCheck = false;

DocumentReader.Instance().processParams().disableFocusingCheck = false
  • Set the maximum value of the deviation of the corners of the document from the 90 degrees value:
DocumentReader.Instance().processParams().perspectiveAngle = 5;

DocumentReader.Instance().processParams().perspectiveAngle = 5
  • Specify the minimal area of an image that a document should cover to be treated as a candidate when locating. The value should be in a range from 0 to 1, where 1 is for the document that fully covers the image:
DocumentReader.Instance().processParams().documentAreaMin = 0.7;
  • Shorten the list of candidates to process during the document detection in a single image process mode. The option reduces the processing time for specific backgrounds:
DocumentReader.Instance().processParams().fastDocDetect = true;
