Open Source OCR in JavaScript

I looked at this recently to try to pick some values off a high res png of a pdf. That was a little too ambitious for this library. It's probably good for smaller images with a few words.

How does Ocrad compare to Abbyy in quality?

http://www.splitbrain.org/blog/2010-06/15-linux_ocr_software... is a very simple comparison (linked from the post).

So with a small enough test set, abbyy is infinitely better

I liked that the demo shows the program failing. Nice to see the capabilities AND the limitations displayed front an center. Definitely impressive.

Would this be an easy way to get OCR into an iPhone app with phone gap?

Could it operate on a live video feed?

I am a bit surprised at how low the accuracy seems to be. Does anyone know if this is typical just of OCR done in JS, or OCR in general? I am aware that at least one or two implementations are extremely good (eg. Google ones) but are those complete outliers?

Doing anything to a live video feed in JS on a phone probably won't be very feasible except for extremely low resolution video.
