ocr - Handwritten recognition software?

    I was wondering if there are some descent handwritten recognition software? I have tried several OCR applications, but they can only work well on scanned printed documents, not on scanned handwritten documents.

    The software can be either free/open source (preferable) or commercial.

    My OS is Ubuntu (preferable), and I also would like to hear about solutions for Windows.

    Although some similar question has been asked before, things can be changed over time.

    Evernote does this. It is multi-platform, but I don't know if the Linux version does that. The Windows version does.

    The software that comes bundled with the Wacom Bamboo Pen tablet seems to do a decent job.

    Though this is using the pen to write with and converting the input to characters in (more or less) real-time rather than taking a scanned image and performing OCR on that.

    Something I've had an occasional need for, but I've never found an application I liked - OCR

    Basically I want to take a photo/scan of a document, and convert it to a text document of some kind (Ideally an option for plain-text, perhaps a .doc or .pages)

    Requirements:

    • Must have a native (Cocoa) GUI, not under X11
    • Free

    Optional pluses:

    • Doesn't require installation, just drag-app-to-Applications-folder (a lot of the OCR utilities I found required libraries to be installed and such)
    • Support images in scanned documents
    • (Apple-)scriptable
    • Open source

    When I researched this topic a while ago there wasn't any free software for any platform that produced reasonable quality output.

    The Optical character recognition article at Wikipedia lists the following free OCR applications:

    I only tried gocr from these, it has no gui and the qualitiy of its output is very low.

    I's suggest to go with a commercial product. Either ABBY Finereader or OmniPage, both of which have OS X versions. They are often bundled with scanners and you can buy them pretty cheap if you don't need the latest version.

    Never heard of any good free OCR for Mac :] There is GOCR, but it is rather crappy. From the low cost apps I would recommend VelOCRaptor. You can try it out for free.

    how about evernote? send them the image, they ocr it for you.

    Sorry, but some command line action is involved in this solution...

    If all you need to do is convert a PDF containing scanned pages into text, the following method has given me good results - where GUI based tools such as VelOCRaptor have failed (I'm talking about a 134 page PDF doc with scanned pages).

    All programs in the tool chain are free or come with OSX.

    • With Preview, save the PDF as TIFF, 150dpi. Make sure you have enough disk space to play with.
    • Run the TIFF through Tesseract (install using MacPorts / Fink)
    • Now you have a raw text file, which can be spell checked using any good editor (TextWrangler, TextEdit, etc.)

    Good luck!

    I have just found something called 'PDF OCR X Community Edition. It's pretty basic - it just gets plain text out without formatting. However, it works quite well. I used it for scanning German, even though officiall it only works with English, and it was ok.

    I haven't been able to find anything for free, but PDFScanner is cheap at $15, is a native OS-X app (Snow Leopard and Lion only, AFAICT), and both scans to an OCR'd PDF and lets you open and OCR an existing PDF. It's the only not-horribly-expensive thing I've found.

    Sounds like if you have microsoft office, there is a tool that can convert images into files. Other than that, i am not seeing anything that is free for os x.

    you did mention you only want a native cocoa app, if you could consider some of the linux builds, you might have some luck as there are a few options there.

    I know it's not free, but I've had reasonably good experience using ReadIris, which you can find for around $60. Basically it will take scans, jpegs or several other image formats, or even PDFs containing scanned data, do OCR on them, and write as PDF ("searchable" -- i.e., text and/or the image itself).
