Mathpix can convert formulas in journal articles into Mathjax/LaTeX code by scanning or taking a picture of them.
Is there a similar way to scan a journal article from the 1970s that was written on an old-fashioned typewriter, either in its entirety or just its maths, so that the formulas written in typewriter are converted to LaTeX code? (Computer Modern font)
This is an example article written by manual typewriter that needs to be converted to LaTeX:
As you can see, formulas written by typewriter make it very difficult to follow any sort of derivation. Images in the article of course can be left as is.
Also, does automated conversion to LaTeX exist somehow at the document level? rather than equation-by-equation and page-by-page conversion
