Each image of a character has a lot of possible textual matches. So in Evernote, there is not a 1:1 correspondence between an image of a character and the recognized text, there’s a 1:MUCH GREATER THAN 1 correspondence. Unlike OCR where each image of a character corresponds to a single character of recognized text, handwriting recognizers will create a probabilistic list of potential matches for each image of character or word. The way systems like Evernote (and Apple and Nebo) work is different than the way a typical OCR works. The issue is that unlike recognizing characters in an image of typed text, handwritten letters can be (far more) ambiguous (than images of typed characters). I am not aware of anything that will make scans of hand-written notes searchable other than Evernote.Īpple Notes and Nebo for iPad will recognize hand-written notes you write within the app.
