According to Wikipedia, "The accurate recognition of Latin-script, typewritten text is now considered largely a solved problem on applications where clear imaging is available such as scanning of printed documents." However, it gives no citation. My question is: is this true? Is the current state-of-the-art so good that - for a good sca...
Here's a tough one: I need to be able to find a word's position and size (its frame) on the screen (its first occurence is enough, from there I should be able to get the next ones). For example, I would like to be able to detect word positions in (but not limited to) Word, Excel and PowerPoint for Mac, as well as Safari and others. Th...
This isn't really OCR, since it's not recognizing characters, but it's the same idea. Anyone know of an image-processing library or established algorithm for retrieving the values from a (raster) plot image? For instance, in this graph, it's hard for me to read exact values with my eyes because there's such gaps between gridlines: I...

Could you recommend some python libraries or source code for OCR and handwritten character recognition? ...
I'm wondering if there is some kind of way to do fuzzy string matching in PHP. Looking for a word in a long string, finding a potential match even if its mis-spelled; something that would find it if it was off by one character due to an OCR error. I was thinking a regex generator might be able to do it. So given an input of "crazy" it w...

I have to pull two pre-printed (not hand-written) fields out of a paper form, such that it can be automatically routed after being scanned. The fields contain batch and item identifiers, like "GG-9192" or "EPN/245G". I've tried the following software: Tesseract-OCR Cuneiform Canon ImageRunner built-in OCR Asprise OCR Java API (demo)...
I have this image: I want to read it to a string using python, which I didn't think would be that hard. I came upon tesseract, and then a wrapper for python scripts using tesseract. So I started reading images, and it's done great until I tried to read this one. Am i going to have to train it to read that specific font? Any ideas on ...

Hey, This is primarily just curiosity but are there any pure java OCR implementations? I'm curious how this would perform purely in java and OCR in general interests me so I'd love to see how it's implemented in a language I thoroughly understand (java). Naturally this would would require that the implementation is open source ... but I...
I am working on a system that is recognizing paper documents using OCR engines. These documents are invoices containing amounts such as total, vat and net amounts. I need to parse these amount strings into numbers, but they are coming in many formats and flavors using different symbols for decimal and thousands separation in the number i...

I am a university student and it's time to buy textbooks again. This quarter there are over 20 books I need for classes. Normally this wouldn't be such a big deal, as I would just copy and paste the ISBNs into Amazon. The ISBNs, however, are converted into an image on my school's book site. All I want to do is get the ISBNs into a string...
At my work, I sometimes have to take some printed source code and manually type the source code into a text editor. Do not ask why. Obviously typing it up takes a long time and always extra time to debug typing errors (oops missed a "$" sign there). I decided to try some OCR solutions like: Microsoft Document Imaging - has built in O...

I've searched around for open source OCR for Chinese. But without any luck there rarely seems to be some open source OCR (for Chinese) that are usable. So I am here wondering: Is there any open source OCR for Chinese that could be used for production environment? What's the main differences when implementing an OCR for Latin-languages...
