The page segmentation mode (PSM) could help you - mode 6 is fairly good at finding various areas of text with images and other noise around but it will sometimes think the surrounding noise is text, so cropping is really the only solution here. Your problem is no different to automatic number plate

Re: [tesseract-ocr] noob - no output black text on white background surrounded by color backgrounds borders and images

One option is try a different PSM mode - 6 may work well. Or you have a card which is great because it means you have repeatable areas of text. Processing the card into cropped areas is possible if your scanning is controlled. Look at what http://card.io do to see an example of getting a good i

Re: [tesseract-ocr] How can i use tesseract-ocr in android studio?

Use https://github.com/rmtheis/tess-two You'll need to compile Tesseract for Android then copy the so libraries into your Android Studio project per the normal way of using JNI libs. Cheers On 4 February 2015 at 10:56, Jorge Alamo wrote: > Hi > > How can i use tesseract-ocr in android stud

Re: [tesseract-ocr] how to pass OCR only in certain part of image (rect XY)?

This is a preprocessing step that you would need to do with an image library, to crop your input image to just the area you want to send to OCR. If your input is a template and scanned reliably, i.e. orientation/size/resolution, then it should be relatively easy to crop the area. If not, then you w

Re: [tesseract-ocr] Help needed in understanding source. New to tesseract.

If you start by learning C++ then you will realise the entry point to a C++ program (main), you can then trace the various calls either manually, methodically stepping through files and functions by searching. You could potentially look at tools that allow call stack debugging/tracing. I am not fam

Re: [tesseract-ocr] Help extracting text from images.

, although this can vary dramatically from font to font. Below an x-height of 10 pixels, you have very little chance of accurate results, and below about 8 pixels, most of the text will be "noise removed". On 13 January 2015 at 21:45, newbie wrote: > Allistair, > Sorry

I'm not sure you can. The tools for training are made for Linux as far as I know. http://blog.cedric.ws/how-to-train-tesseract-301 However, once trained, you can use the training file in your Windows Tesseract. On 12 January 2015 at 16:07, Albert Bonn wrote: > How do I do it with windows? > >

Re: [tesseract-ocr] OCR of a heart rate monitor

Even totally cleaned up of the surrounding frame and gradiented backdrop on the screen, Tesseract does not recognise the large numbers for me. That may mean you need to acquire this font and train Tesseract yourself explicitly. Tesseract is trained with a whole bunch of fonts but probably not this
