  I apologize for the delay with response caused by the state holidays in Russia.

  When you use the processFields method there is no possibility to adjust image preprocessing settings. By default in this scenario the image files are subjected to additional processing, such as:

  • GeometryCorrectionMode = GCM_Auto - image geometry correction will be performed, if it is necessary. ABBYY will determine automatically, whether the processed document is a photo and if it is, will perform geometry correction.
  • ResolutionCorrectionMode = RCM_Auto - which means that if resolution of the image is suspicious, ABBYY should automatically detect image resolution and change it.
  • CorrectSkew = TSPV_Auto - ABBYY will automatically determine if this processing mode should be used, depending on the situation (image characteristics, etc.).
  • CorrectSkewMode = SkewByHorizontalText + SkewByVerticalText - the image skew angle is corrected based on horizontal and vertical text lines.

  Unfortunately, Cloud OCR SDK does not support automatic layout analysis for field-level recognition, so you need to set up some certain recognition parameters for the fields to "tell" the service that the text to be recognized has the certain format. The coordinates of the fields also must be specified manually. This approach is applicable, only if the recognized documents are well-structured, have a known layout and are not different from each and other.
