Nice project. In my tests, recognition was poor, but I'm sure that depends on my inability to fine-tune it. I was looking for a lazier solution, but this might be a fine choice especially if you want more control and can dedicate time to it.
In particular it has problems with encoding and math, often churning out lots of greek characters. The windows version doesn't. Definitely a nice option for extracting text, but there's no OCR capability that I can see. Now you need to clarify: is your problem to extract text from poor-resolution image such as generated with VGA cam, poor scanner or distant picture?
Then your problem is different and requires physical consideration of things such as super-resolution. Please, ask more specific and shorter questions so they can be answered. I suggest you to simplify this question to one feature you want. If you want something more, ask a new question.
This does not answer the original question. It looks like a cool solution, although I've found the OCR backend, Tesseract, rather disappointing quite certainly because of my own limitations in correctly configuring it. I love OCRmyPDF, see my answer below which explains how to install and drag-and-drop automate it quickly and painlessly with docker. To install required tools, on OSX you may install it via Homebrew : brew install imagemagick jpeg libpng ghostscript tesseract On Linux use apt-get or yum instead of brew.
The example seems to not work with multiple PNG's. I made a loop and generated multiple text files, that way i didn't get s of weird errors. I also installed tesseract-lang and then added the -l deu parameter to process localized text and it improved the recognition quality by a lot. It would be overkill if you're only using it for scripted OCR - but it's a very good app. Diggory Diggory 3 3 gold badges 7 7 silver badges 16 16 bronze badges.
And user can somehow "script" it? Yes - the app has a good AppleScript Dictionary, which amongst other things, allows you to convert images stored in the app into searchable PDFs. It is a fascinating concept if done well Is it possible to export your projects from this software with the OCR?
If not, some very simple OCR lib and then some linguistic analysis lib may work the best. It can recognise in several languages: i. Show 4 more comments. Again: I am not looking to parse or extract text that is already there. I am looking to recognize text OCR in PDF file that are essentially images, bitmaps; they do not originally contain any text.
You want to automate the addition of OCR layer so you can search over different kinds of documents even without "searchable text"? If you could do this, you could search over all documents in Finder -- you understand? I am surprised if Apple does not do this in coming upgrades For this type of self-directed application, I'm a big fan of Hazel.

We're trying to find the best answers and those answers will provide info as to why they're the best. Explain why you think the software you recommended is better than others out there. In general, link-only answers are susceptible to being deleted so you always want to make your answer inclusive of all relevant info.
See How to Answer on how to provide a quality answer. If you: install Docker for your Mac and then create a new Automator app with these contents inside a "Run a Shell Script" action. You can test it in Automator itself with "Get specified Finder items" action as input to this.
This switch is recommended for table OCR, receipt OCR, invoice processing and all other type of input documents that have a table like structure. New: We implemented a second OCR engine with a different processing logic. It is better than the default engine engine1 in certain cases. So we recommend that you try engine1 first since it is faster , but if the OCR results are not perfect, please try the same document with engine2.
So you can easily switch between both engines as needed. Please report any bugs or feature requests to bug-ocr-ocrspace at rt. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.
