I'm trying to use MODI to OCR a window's program. It works fine for screenshots I grab programmatically using win32 interop like this: public string SaveScreenShotToFile() { RECT rc; GetWindowRect(_hWnd, out rc); int width = rc.right - rc.left; int height = rc.bottom - rc.top; Bitmap bmp = new Bitmap(width, height)...

I decided to do a project for fun where I want to take as input the image of a playing card and return its rank and suit. I figure that I only need look at the upper-left corner, since that has all the information. It should be robust - if I have a large image of an Ace of Diamonds, I should be able to scale it anywhere from 20 to 200% a...
I'm interested in simple OCR methods and algorithms. And with simple I mean simple! Best would be a tutorial/article/documentation without dependencies on 3rd party librarys if that's even possible. I would really like to build up my knowledge from the ground up. The programming language doesn't matter. Thanks in advance! Edit: An ...
I'm using PRIME RECOGNITION's OCR program and I was wondering if there was a program out there than can "make sense" of graphs, charts, and forms. I need them to have read-order and text-searchable. So instead of using lots of figure and text zones to describe them, is there a way to enter in the data and have a program recreate it in a ...
I am using Tesseract OCR (via pytesser) and PIL (Python Image Library) for automated test of an application. I am checking that the displayed text is ok by making a screenshot and getting the text thanks to tesseract. I had some issues in the beginning and it seems to work better since I have increased the size of the screenshot thanks...
I've written an OCR wrapper library around the Microsoft Office Document Imaging COM API, and in a Console App running locally, it works flawlessly, with every test. Sadly, things start going badly when we attempt to integrate it with a WCF service running as an ASP.Net Web Application, under IIS6. We had issues around trying to free u...
I'm trying to do some simple and fast image comparison of similarity. All of the images are of the same size. The color differences are quite delicate. Currently, I calculate a difference measure by calculating the sum of difference in the R,G and B values between the images, sort of a Hamming distance. That is, Abs(P1.R - P2.R) + Ab...
I am looking for a way to determine the most "different" or "recognizable" N ASCII characters... For example, if N = 10, what would be the most different N characters in the ASCII set from 0x21 to 0x7E? Obviously, the character "X" is very different than "O" (the letter), but "O" (the letter) is very similar to "0" (zero). Assuming a ...

I have a set of images over which I run an OCR application. This process results in a XML file with character offsets. Then I convert the images to PDF using Acrobat 9. Now, I would like to add the XML file information as an invisible text layer into the PDF in order to achieve a searchable PDF. Is there an easy and free way? Some detai...
I have a bunch of PDF files that came from scanned documents. The files contain a mix of images and text. Some were scanned as images with no OCR, so each PDF page is one large image, even where the whole page is entirely text. Others were scanned with OCR and contain images and searchable text where text is present. In many cases ev...
