Hello list, it's most likely not just mine experience, that recognizing math expressions in image documents has been always difficult, in fact mostly inpossible. There are some tools around promising to solve this issue, but none of them was by any means useful at least for me, as they were unable to recognize even the most basic formulas. But then, some time ago, a service called Mathpix has appeared, making use of deep learning and neural networks to recognize math expressions and scientific figures. From my tests, its accuracy is truly impressive, but there is one drawback. You can't feed it an image of the whole page and get the math, you need to graphically crop only the mathematic content you want to recognize. So, a question arises, how could a blind person crop a formula from image? math_scanner tries to answer this problem. It makes use of the fact, that OCR engines can recognize the surrounding text around formulas just fine, with the math content being a clear hole easily detectable by a blind reader. math_scanner tracks positions of individual characters and allows the blind user to use them to surround the math content and get it recognized. From early tests, this approach seems to really work, and I was able to read documents that were totally unreadable by any other tool! You can read more, as well as get the program on it's repository page: https://github.com/RastislavKish/math_scanner I'll be happy to hear your experiences, with learning as well as results. I found the concept quite difficult to explain, even though it's natural once you get it, so if you have any questions, feel free to ask. Anyway, happy math reading!
