OCRFeeder – document layout analysis and optical character recognition system

OCRFeeder is a free open source software desktop OCR suite for the GNOME desktop environment. It converts paper documents to digital document files or makes them accessible to visually impaired users. OCRFeeder was created to allow users to easily convert document images (for example, a PNG image with text) into editable documents (for example, an ODT version with that text).

OCRFeeder will automatically outline its contents, distinguish between what is graphics and text and perform OCR over the latter. It generates multiple formats.

It features a complete GTK+ graphical user interface that allows the users to correct any unrecognized characters, defined or correct bounding boxes, set paragraph styles, clean the input images, import PDFs, save and load the project, export everything to multiple formats, etc.

Features include:

  • Simple graphical user interface.
  • Configurable.
  • Views: Zoom in / out, Normal Size, and Best Fit.
  • Import data from PDF or graphic files.
  • Grabs images direct from the scanner.
  • Unpaper image processor: Black filter, noise filter intensity, grey filter size.
  • Image Deskewer – deskewing an image makes it easier for the software to recognise the image. This option can be performed automatically each time an image is added.
  • Choose the language for the OCR engine.
  • Spellchecker.
  • Automatic recognition performs some complex operations.
  • Generates three document formats: ODT, HTML and Plain Text.
  • Supports OCR Engines: Cuneiform, Tesseract, GOCR, and Ocrad.
  • Supports: English, Czech, Danish, German, Spanish, French, Galician, Italian, Norwegian, Portuguese, Romanian, Slovenian, Swedish and Chinese.
