What’s New

  • Text analysis improvement
    Updated the algorithm that searches for text on video frames. New method is more stable and the average number of character misses is 5% less than before.
  • iOS: changes in errors handling
    All errors are now returned by the onError method of RTRRecognitionServiceDelegate. An error occurs if you try to transfer RTRRecognitionService to invalid state, for example, specifying a non-existent recognition language. On error, RTRRecognitionService state remains unchanged (for example, the recognition language is not changed).
