Typically if you've forgotten or have never seen a symbol in a math equation before you are forced to read a large part of the context you found it in and guess which name that symbol has. That is too time consuming for me and my picture memory sucks so I forget the meaning of these symbols all the time. Comparing the symbols with a reference list is also rather time consuming, since you need to have the right list and you need to compare each symbol linearly.
In a perfect world people would stop using pictures and use Unicode in their math-equations but nope that's not the kind of world we live in. I was thinking I could program this as an exercise after I've completed my course in Image Recognition but wondering if there already is any software like this.
Does anyone know of software that can identify symbols in math images, or some other easy way?
