Ha I was going to say, I was trying to read receipts and Tesseract was having problems, those are machine-printed not hand written. Granted supposed to clean up/up contrast/etc... but yeah. Scanning a screenshot of a website though accuracy is almost 100% every time eg. just black/white text.
- dr_zoidberg 6y agoIt's usually better to segment the text on the image (and twek the perspective if necessary) to help tesseract extract the text. All the "easy" preprocessing that can be done beforehand helps a lot. I understand that Google Vision Services doesn't need these kind of adjustments (or maybe they do them automatically?), which makes for an easier time/less code, but setting up the account sure looks like a lot of work from the article!
- jcun4128 6y agoThat's a good tip about the segmenting text, will have to keep that in mind next time. I like the local aspect, one project I have in mind is a hand writing to printed letters for note taking/tablets. Not a new concept I think one drive has it, but it would be neat to train it on your own writing. Why not Zoidberg
- dr_zoidberg 6y agoIf you want to train your own net for handwritten letters, you can start with EMNIST[0] and then move on from there. [0] https://www.nist.gov/itl/products-and-services/emnist-dataset https://www.nist.gov/itl/products-and-services/emnist-datase...
- jcun4128 6y agoThanks, yeah it's an ambitious project. It's cool but has no real gain immediately. Maybe if I was a student/used a tablet everyday.
