The Ocrad manual contains a section on the used algorithms, e.g.:ĥ) Detect characters and group them in lines.Ħ) Recognize characters (very ad hoc one algorithm per character).ħ) Correct some ambiguities (transform l.OOO into 1.000, etc). In a business document, it missed an underlined word, where cuneiform/tesseract/gocr didn't. Ocrad example call: $ ocrad -F utf8 image-0001 ( -l specifies the language of the source document) ocrad You can disable the layout algorithm like this: $ cuneiform -singlecolumn -l ger -f text -o foo.txt image-0001
it does not error out on unknown options. in one-column documents paragraphs are often randomly shuffled around its layout algorithm is simply broken, i.e. Segmentation faults with various packages and releases. CuneiformĬuneiform OCR performance isn't that bad, but it isn't actively maintained (last release in 2011, version 1.1) and easily crashes and has some other issues: often it falsely detects single characters in dust pixels (outside of any textual context) and easily introduces single character errors in well-known words. The Tesseract version 3 performs relatively bad even on good quality input images, i.e. With the new LSTM model, Tesseract takes some inspiration from the OCRopus research project. Support for quite many languages/scripts is available in the form a downloadable trained data sets, e.g. List installed languages: $ tesseract -list-langs Print the recognized text to stdout: $ tesseract -oem 1 -l deu page page-0001.png stdout #Abbyy cli ocr for linux pdf
$ tesseract -oem 1 -l deu input.list output pdf Its OCR performance is much better than the previous OCR model used in version 3.Įxample (produce a PDF file output.pdf with a text layer for a scanned german document): $ echo page-*.png > input.list

This makes the software fully interoperable with other products and the files completely independent of any single developer.As of 2020, the best available open source OCR software is Tesseract 4 with its new LSTM neural network OCR model. Standardization - The PDF Compressor produces standardized PDF/A.

Integrated OCR solution - Integrated ABBYY OCR technology allows full text searching for all PDF and PDF/A files.For years, the PDF Compressor has been successfully processing everything from occasional jobs to huge numbers of documents utilizing automated, high-volume processing capabilities.
Mass-processing and scalability - The PDF Compressor is flexible enough to meet almost any document management need. In addition, the documents are read out using Optical Character Recognition (OCR) and are thus available in a full text searchable PDF format.Īdditional benefits of Foxit's PDF Compressor include: The lossless MRC process reduces the file size by a ratio of up to 100: 1 or more without affecting the quality of the document. Outstanding image quality and text legibility are preserved, while storage costs and bandwidth requirements are drastically reduced. The PDF Compressor leverages mixed raster content (MRC) layer-based compression technology that compresses with ratios of 1:100 or better. "We have been long standing supporters of Linux, and that matched with a strong demand from PDF Compression customers made this roll-out a no-brainer." "We are excited that organizations using Linux servers will now be able to enjoy all the benefits of Foxit's industry-best PDF Compressor," said Gert Michiels, Director of Product Management for PDF Server products at Foxit Europe.
