Example 8 with TextBlock

use of com.google.android.gms.vision.text.TextBlock in project Moneycim by volkansahin45.

the class OcrDetectorProcessor method receiveDetections.

/**
 * Called by the detector to deliver detection results.

 * equivalent detections by tracking TextBlocks that are similar in location and content from
 * previous frames, or reduce noise by eliminating TextBlocks that have not persisted through
 * multiple detections.
