tesseract

I'm currently developing an application which uses the iOS enabled device camera to recognise equations from the photo and then match these up to the correct equation in a library or database - basically an equation scanner. For example you could scan an Image of the Uncertainty Principle or Schrodinger Equation and the iOS device would be able to inform the user it's name and certain feedback. I was wondering how to implement this using Xcode, I was thinking of using an open-source framework such as Tesseract OCR or OpenCV but I'm not sure how to apply these to equations. Any help would be

I'm using tesseract to recognize a serial number. This works acceptable, common problem like false recognition of zero and "O", 6 and 5, or M and H exists. Beside by this tesseract adds spaces to the recognized words, where no space is in the image. The following image is recognized as "HI 3H" . This image results in " FBKHJ 1R1" So tesseract added a space, although there isn't really a space in the image. Is there a possibility parametrize the spacing behavior of tesseract? Edit I'm sorry, have forgot to add, that I also have serial numbers which include spaces. So I cannot delete all spaces

I'm curious about how I may be able to more reliably recognise the value and the suit of playing card images. Here are two examples: There may be some noise in the images, but I have a large dataset of images that I could use for training (roughly 10k pngs, including all values & suits). I can reliably recognise images that I've manually classified, if I have a known exact-match using a hashing method. But since I'm hashing images based on their content, then the slightest noise changes the hash and results in an image being treated as unknown. This is what I'm looking to reliably address with

I have been working on android from 6 months. So I have basic idea about Android development. Now I want to develop an OCR Android app using Tesseract. For that I have downloaded android-ndk-r6b, tess-two from Tesseract, Cygwin for Windows and installed C/C++ developer in Eclipse. And I followed these two links: 1.http://www.itwizard.ro/interfacing-cc-libraries-via-jni-example-tesseract-163.html 2.http://gaut.am/making-an-ocr-android-app-using-tesseract/ but I got stuck in between. I mean I am not able to configure these things together. Can anyone suggest me how to configure tesseract in

Using tesseract-ocr #3.02.02. The basic usage of tesseract is tesseract sourc.png result and result.txt is generated. To get the result text, I have to cat this file. Is there any options to dump the result in stdout? Simeon Visser You should upgrade to v3.03 where support for stdout was added . The solution is: tesseract input.jpg stdout But you need at least version 3.03 来源： https://stackoverflow.com/questions/24347819/can-tesseract-ocr-put-the-result-to-stdout
