Image processing options
To customize the scanning and opening of pages in ABBYY FineReader, you can:
- enable/disable background recognition in the PDF Editor
- enable/disable automatic analysis and recognition of pages when they are added into the OCR Editor
- specify image preprocessing settings
You can select desired options either when opening a PDF document, images or scans in the New Task Window or on the Image Processing tab of the Options dialog box (click Tools > Options... to open this dialog box).
Any changes you make in the Options dialog box will only be applied to newly scanned/opened images.
The Image Processing tab of the Options dialog box contains the following options:
Enable background recognition in the PDF Editor
background recognition will be used for all pages you open in the PDF Editor. Background recognition allows you to search and copy text even in documents that do not have a text layer (e.g. documents that contain only scans or that were created from images). No permanent changes are made to the document itself.
On this tab, you can also specify the OCR languages.
If you want to enable other users to carry out text searches in this document, click File > Recognize Document > Recognize Document....
Automatic analysis and recognition of images added into the OCR Editor
By default, pages are analyzed and recognized automatically, but you can change this behavior. The following modes are available:
- Recognize page images (includes preprocessing and analysis)
When images are opened in the OCR Editor, they will be automatically preprocessed using the settings selected in the Image preprocessing settings (apply to conversion and OCR) group of settings. Analysis and OCR are also performed automatically.
- Analyze page images (includes preprocessing)
Image preprocessing and document analysis are performed automatically, but OCR has to be started manually.
- Preprocess page images
Only preprocessing is carried out automatically. Analysis and OCR have to be started manually. This mode is commonly used for documents with complex structures.
If you do not want the images you add to be automatically processed, clear the Automatically process page images as they are added to the OCR Editor option. This lets you quickly open large documents, recognize only select pages in a document, and save documents as images.
By default, ABBYY FineReader lets you automatically correct common defects on scan and digital photos.
Select Specify settings manually to manually specify settings recommended for improving recognition quality:
- Split facing pages
Split facing pages The program will automatically split images that contain facing pages into two images containing one page each.
- Correct page orientation
The orientation of pages that are added to an OCR project will be automatically detected and corrected if necessary.
- Use recommended settings for better OCR
The program will automatically choose and apply the required preprocessing settings.
To display all the settings, click Show Custom Settings:
- Deskew images
The program will automatically detect skewed pages and correct skew if necessary.
- Straighten text lines
The program will automatically detect uneven text lines on images and straighten them without correcting trapezoid distortions.
- Correct image resolution
The program will automatically detect will automatically determine the best resolution for images and will change the resolution of images when necessary.
- Detect page edges *
The program will automatically detect and crop image edges.
- Whiten background *
The program will automatically whiten backgrounds and select the best brightness setting.
- Reduce ISO noise *
The program will automatically remove noise from photographs.
- Remove motion blur *
The sharpness of blurry digital photos will be increased.
- Correct trapezoid distortions *
The program will automatically detect trapezoid distortions and uneven text lines on digital photographs and scans of books.
- Fix inverted colors on image
When appropriate, the program will invert the colors of an image so that dark text is printed on a light background.
- Convert to black and white
The program will convert color images to black-and white This will greatly reduce the size of the resulting OCR project and speed up OCR. We do not recommend black-and-white conversion for photos, magazine pages, and texts in Chinese, Japanese, and Korean.
- Remove color marks
The program will detect and remove any color stamps and marks made in pen to facilitate the recognition of the text obscured by such marks. This option is designed for scanned documents with dark text printed on a white background. Do not select this option for digital photos and documents with color backgrounds.
* For digital photos only.
To display only the recommended settings, click Hide Custom Settings.
Select No preprocessing option to disable all of these options when scanning or opening document pages. You can still apply any desired preprocessing in the Image Editor of the OCR Editor. See also: If your document image has defects and OCR accuracy is low.
