Indeed, it keeps trying to interpret it as a sum. Though perhaps the pi symbol is confusing it. I actually have an archive of all my physics degree notes - it'll be interesting to see how well it handles them (e.g. equations not written with it in mind, at all)
Unless you wrote your notes digitally, it won't work: "the parser accepts input files in two formats: InkML and SCGINK". These are stroke based formats - the recogniser needs to know which points are connected, and possibly which order things were drawn.
Oh, I was misinterpreting the definition of handwritten. A pity.
Edit: Though, thinking of it, does anyone know of research into decomposing images of text into stroke patterns? It seems like it's a problem that must have had some decent research on it...
