Is there a tool for exporting equation images to TeX? Probably something related to OCR. I have a lot of image-equations in a word document that I'd like to convert to TeX.

Note that the equations are actually images, so no word2tex-like apps would help.

N.B.: Using this to copy equations from Wikipedia is 100% pointless, because you can also just select the equation with your mouse and press CtrlC, which will put the LaTeX source of that equation in your clipboard.

In addition to Infty, there's also FFES --- the Freehand Formula Entry System. Paper on it here: http://academia.edu/156023/Handwriting_Speech_for_Computer_Entry_of_Mathematics and it's available here: http://www.cs.rit.edu/~rlaz/ffes/
