I want to create an app that you can take a photo of a chemical displayed formula and it will give you its name and formula. I want to use google vision, but I am not sure if google vision can recognize characters or can it only recognize words? Also, is it easier to get the location of characters using google vision or tesseract?

Edit: I am currently using tess two, I am able to display the characters of the words, but unsure of how to get the location of each character.

  • I am currently trying Tess-Two. I have read that it is hard to get the location of characters. I believe it gives the location in the HOCR file, however, I am having troubles getting the HOCR file/ – Nima Hojat Nov 27 '17 at 14:32
