Step 2: Layout Analysis Keys

--prohibitModelAnalysis

  • New CLI 11 R2
  • If this option is not used, typical variants of page layout will be analyzed during page analysis, and the best variant will be selected, which can improve the recognition quality. With this option only standard page layout analysis will be performed.
Key Parameters Default
-aprma no
- -prohibitModelAnalysis

--detectBarcodes

  • Detects barcodes and creates barcode blocks during the page layout analysis.
  • If this key is not available, barcodes may be detected as blocks of some other type (e.g. pictures).
Key Parameters Default
-adb no
- -detectBarcodes

--detectInvertedImage

  • Detects whether the image is inverted (white text against black background).
Key Parameters Default
-adii no
- -detectInvertedImage

--detectImageOrientetion

  • Detects page orientation during layout analysis, and if it differs from the normal, rotate the image.
Key Parameters Default
-ido no
- -detectImageOrientetion

--dontDetectPictures

  • The pictures are not detected during layout analysis.
Key Parameters Default
-adp no
- -dontDetectPictures

--dontDetectTables

  • The tables are not detected during layout analysis.
Key Parameters Default
-adt no no
- -dontDetectTables

--fastObjectsExtraction

  • Detect all text on an image, including text embedded into the image.
  • Reading order is not changed to provide ability for further full-text search.
Key Parameters Default
-aftda no
- -fastObjectsExtraction

--enableTextExtractionMode

  • Layout analysis will detect isolated text blocks that can be located anywhere on the page.
  • Model analysis will not be performed.
  • New CLI 11 R1
Key Parameters Default
-aetem no
- -enableTextExtractionMode

--detectVerticalEuropeanText

  • Layout analysis will look for vertically oriented European text.
  • New CLI 11 R1
Key Parameters Default
-advet no
- -detectVerticalEuropeanText

--aggressiveTableDetection

  • Layout analysis will try to find as many tables as possible on the page.
  • This option is recommended only for the documents which contain a lot of tables.
  • New CLI 11 R1
Key Parameters Default
-aatd no
- -aggressiveTableDetection

--enableAggressiveTextExtraction

  • Detects all text on the image, including low-quality text.
  • This processing mode may lead to mistaken vertical rearranging of the horizontal text.
  • New CLI 11 R1
Key Parameters Default
-aeate no
- -enableAggressiveTextExtraction

--detectTextOnPictures

  • Layout analysis will detect all text on an image, including text embedded into pictures.
  • Reading order is not changed to provide ability for full-text search later.
  • New CLI 11 R1
Key Parameters Default
-adtop no
- -detectTextOnPictures

--prohibitClockwiseRotation

  • Disables clockwise page rotation when selecting the page orientation. This key can not be used with the
    • -apccw or
    • -apud key.
Key Parameters Default
-apcw no
- -prohibitClockwiseRotation

--prohibitcolorImage

  • Uses only black-and-white plane during page layout analysis.
Key Parameters Default
-apci no
- -prohibitcolorImage

--prohibitCounterclockwiseRotation

  • Disables counterclockwise page rotation when selecting the page orientation.
  • This key can not be used with the
    • -apcw or
    • -apud key.
Key Parameters Default
-apccw no
–prohibitCounterclockwiseRotation

--permitModelAnalysis

  • Note: Starting from release 2 this option is obsolete. Using it does not affect processing. The opposite option -aprma / –prohibitModelAnalysis should be used in case model analysis needs to be prohibited.
  • Typical variants of page layout will be analyzed during page analysis, and the best variant will be selected, which can improve the recognition quality. If the best variant of the page layout cannot be selected, standard page layout analysis will be performed.
  • Key updated in CLI 11 R1
Key Parameters Default
-apma no
- -permitModelAnalysis

--prohibitUpsidedownRotation

  • Disables upside-down page rotation when selecting the page orientation.
  • This key can not be used with the
    • -apcw or
    • -apcw key.
Key Parameters Default
-apud no
- -prohibitUpsidedownRotation

--dontClearBackgroundNoise

  • Prevents ABBYY FineReader Engine from removing the background noise from a temporary image used for recognition.
Key Parameters Default
-it no
–dontClearBackgroundNoise

--sourceContentReuseMode

  • Specifies how to use the text and image layers of the source PDF file.
  • New CLI 11 R1
Key Parameters Default
-scrm Auto
DoNotReuse
ContentOnly
Auto
