Google sponsors the development of an open-source OCR software at the IUPR research group. "OCRopus is a state-of-the-art document analysis and OCR system, featuring pluggable layout analysis, pluggable character recognition, statistical natural language modeling, and multi-lingual capabilities."
"The goal of the project is to advance the state of the art in optical character recognition and related technologies, and to deliver a high quality OCR system suitable for document conversions, electronic libraries, vision impaired users, historical document analysis, and general desktop use," explains Thomas Breuel, who leads the project.
The software is partly based on Tesseract, the best open source OCR engine available for now. While the project is expected to be released at the end of next year and will be used for Google's book scanning project, the team has some interesting applications in mind:
* a web service interface
* PDF, camera, and screen OCR
* integration with desktop search tools: Beagle, Spotlight, Google Desktop
The most popular OCR software are ABBYY FineReader, Omnipage, Readiris and Presto OCR, but they're pretty expensive (starting at $100). A decent solution to perform OCR on a document is Microsoft Office Document Imaging, included in Microsoft Office XP/2007. Microsoft Office OneNote 2007 also lets you OCR imported images. A free online alternative is Scanr, a site that lets you digitize documents by sending a mobile phone photo by email.
Dear Google,
ReplyDeletePlease release an OSX version ASAP!! This sounds great!

It's nice to see investment in basic OCR technologies. In the past, open source OCR really hasn't come close to the performance level of commercial packages (scanR has 2 OCR vendors).
ReplyDeletescanR will extract the text and create a searchable PDF file from any picture of a document sent to doc@scanR.com. You can search your documents on www.scanR.com or forward the PDF in email. For business cards, scanR will tag each word with its context and create a vCard. Just send pictures of business cards to bc@scanR.com. We'll even sync them with your Plaxo account.
Thanks for the post on scanR.
Fantastic. Well done. As a visually impaired person, this sounds like it could have great impact on the Assistive Technology Market. Specifically on the price of other applications for this area such as Kurzweil 1000.
ReplyDeleteWith Google's statistics of words/phases and images, the OCR will be able to do more intelligent works while improving accuracy.
ReplyDeleteOne day, we can use ocr.google.com.
ReplyDeleteI upload a few images of scanned documents, then Google will return text or PDF.
I think Google will probably charge a reasonable fee for such service. Google will encourage users to store the text of PDF file online, so Google can easily analyze the amendments made by users, in order to improve the models of recognizing words.
If the people from scanr.com can make the service (partially) free, I'm sure Google's online OCR service will be free. With some limitations.
ReplyDeleteThey could also add OCR options when you import PDFs in Google Docs, for Gmail attachments, in Google Desktop etc.
This is just the right thing to invest money into; even without charging for the end product.
ReplyDeleteI have this sort of Google-hostile human-friendly site ( grafted.interface ) and it seems that it is scheduled for an involuntary SE optimization in the near future.
For some sort of feedback check out my short sort of treatise ( structural formulae searchability ) on how SEs have neglected a sort of information very important in many fields of science which is very important IMO
There's bound to be an ad-funded business model for this - users will be gasping for it!
ReplyDeleteI'd love to have something like this. I've just tested a bunch of OCR converters and they really didn't do the job -- they fail when it comes to converting pages that have both text and images on them. I'm trying to convert pdfs and save them as Microsoft Word documents (or Powerpoint) and nothing quite seems to do what I want which makes me reluctant to purchase something without trying it.
ReplyDeleteHope you can work with the Open office and SANE guys to create an integrated system (i.e. scan a document and it automatically gets OCRd and appears in OpenOffice).
ReplyDeletewhat about using your digital camera for OCR? You should check out TopOCR This is freeware and has more features an accuracy than some of the expensive commercial versions.
ReplyDeleteHello everyone ,
ReplyDeleteCan someone tell me how can we reach Google to ask it for sponsoring our Graduation Project?
Who do we contact
Thanks in Advance :)
There is also OCR Terminal - a web service that allows you to upload scanned documents/ images in a variety of formats and download OCRed text in doc, rtf and so on.
ReplyDeleteYou also have mobitra.mobi/image to get the recognition and/or translation of the text contained in an image, specially designed for mobile phones.
ReplyDeletethe link of the explanation
ReplyDeleteThis is absolutely fantastic project. Once this is complete I am sure the way we deal with the documents will undergo a sea change and more amd more software products will be built around it. Google! all the best
ReplyDeleteJust trying to unzip the download file is a pain.
ReplyDeleteIt is a pain to download and get working and there is also a lot of work to be done on it, but the idea of having an open source OCR program being actively developed is exciting!
ReplyDeleteIf there is a god there will be a release for OS X.
ReplyDeletein that case i'm god, im gonna port it to osx this weekend :D
ReplyDeleteHey I'm doing an OCR software project which should extract the text from the camera captured image file. Is there anybody who can help me out? I'm pretty short of time.
ReplyDeleteThis project will be really useful. There are some other free OCR tools available Best PDF OCR Tools to Convert Scanned images to Text / Word Documents
ReplyDeleteHas anyone tried WatchOCR from http://www.watchocr.com ? It is simple, open source, and seems to work very well for making searchable pdfs.
ReplyDeleteWatchOCR is really nice OS with OCR system and works fine ! I stated to script an GED web interface (PHP/Mysql) with pdftotxt for parsing content and inject into database.
Deleteone more ocr software. works good for me.
ReplyDeleteThis is great. I am sure the OCR will be more intelligent and improved I am sure.
ReplyDeleteThis is great im visually impaired the info you have provided is invaluable!
ReplyDeletePrimeOCR (primerecognition.com ) is a commercial package.
ReplyDeleteI use ABBYY FineReader,and I can say that this is a wonderful software! I can't but agree with the statement that FineReader is pretty expensive, but still it costs its money. Besides, it supports arabic OCR!
ReplyDeleteFrom where i can get this software a complete version?
ReplyDeleteI am trying to make it for my own language.
ReplyDeleteWhen choosing OCR software, I always think about the recognition accuracy and recognition speed. As I know, Yunmai Technology is also very professional on OCR technology. Yunmai Document Recognition is really great for me. The average time for recognition of a document less than 6 seconds. The recognition accuracy can reach 99%. It can convert documents into PDF, Word, Text format files.
ReplyDeletepassword using that,,,
