I have been given a PC project at High school that is supposed to calculate equations from an image. Obviously i will need some form of image recognition to do this, so i searched the internet for quite some time. I have found two ways to solve this. First one including an external program like Neuroph(a program working with neural networks) and the other being a Java OCR project found here .

The problem i have with Neuroph is that i would have to split the equation image into multiple other images, each containing one character, since the program compares the images in whole. I found this a little tricky to do so i wanted to see if there was a different solution.

And so i came upon the OCR project. Unfortunately i couldn't find much information of its possibilities on the internet, so i am unsure if it can solve the problem i had with Neuroph (having to split the image)

In conclusion i have the following questions:

  1. Can the Java OCR detect characters on the image?(the splitting problem)
  2. Does anyone know of a good way to split an image into multiple others, each holding one character? (I can do the rest with Neuroph)
  3. Is there a 3rd way to make the project?

  • My instinct tells me you are over-complicating the problem and arbitrary character recognition might not be necessary. Are there not stipulations about the input image and/or characters that will be used? – Dave Jun 10 '15 at 22:51
  • @Dave Now that you mention it nothing other than the input image having to actually have an equation on it. – LordElemelon Jun 11 '15 at 08:34

You can use this SDK to do it easily (I know it works on Android, iOS, and Windows Phone but I'm not sure about other OSes). You will need to contact the company for the maths SDK though. Also, if you want to see how it works, search for 'PhotoMath' on your phone's store.

  • It seems it is a phone app, or i haven't understood it good? I am supposed to make a PC project though, not a phone one. Sorry for not coming clear on that. I edited the post so no one else gets misinformed – LordElemelon Jun 10 '15 at 22:40
  • @LordElemelon oh, I'm not too sure about that then, but this looks promising: http://www.abbyy.com/ocr-sdk-windows/ – kabiroberai Jun 10 '15 at 22:42
  • I've requested for Trial and am hoping to get approved. Thanks! – LordElemelon Jun 10 '15 at 22:49
