This would be really cool! We would welcome a pull request and / or link to any downstream project working on this. In a similar vein, we've been considering adding the stroke width transform [0] as an optional preprocessing step.

Yep, this is completely client side :) You can even host the external language files yourself as described in the readme: https://github.com/naptha/tesseract.js#local-installation

If you want to use a real Promise, you can wrap the call to recognize in Promise.resolve: Promise.resolve(Tesseract.recognize(myImage)).then(result => console.log(result))

That's interesting! Given that Tesseract.js wraps an Emscripten'd copy of Tesseract, I would have expected close to identical performance. This might have to do with the way we threshold images, with the age of the tesseract versi

Although Google's API is certainly better, Tesseract.js should work similarly if you increase the font size. Screenshots taken on 'retina' devices are around the smallest text it can handle well. Edit: A screenshot of the sam

Did you try increasing the font size a bit? On a retina macbook (so effectively ~2x bigger font) I get: Excited about this... but the OCR quality seems to be very bad. Maybe it's not optimized for recognizing black text on a white back

As another commenter mentioned, Tesseract.js won't perform very well on 'natural' images (e.g. the very light text you tried). It should work better if you feed it a screenshot of the black text at the top of the demo page th

It's a wrapper around an Emscripten port of that library. See https://github.com/naptha/tesseract.js-core

First, you make up some names and give each name a number. Then you draw shapes based on the names, not the numbers. For example, you might make a number called my_cool_number, and set it to 10, and then say "draw a circle my_cool_numb

If AR is VR with transparency, wouldn't that mean that AR is a superset of VR, in the same way that RGBA images are a superset of RGB images? Or looking at it another way, isn't VR just AR with the lights off?
