Hi! I learned today about Ocrad.js which is
my first idea was to grab image from the camera and read text being on that image. I started
by learning how to capture video in HTML5. Which is nicely described on html5rocks.com
Then, I found this glfx.js library that allows me to add some filters, apply some fileters
on the image. Like: change brightness, change contrast and do some sharpening. Which I will need to improve image from camera before extracting text. Lastly, I found a small jQuery plugin
that allowes me to easily crop images. I ended up with this. It’s a very simple demo. I will
now allow my browser to use the camera. Here I am and here is text that I will try to extract. Let me make a proper snapshot. OK. This should work. Now, I crop out the text that I want
to extract. OK. Now we have an image that we will try to read using Ocrad.js library.
As you can see it works very nicely. Actually, from what I tested all printed stuff, all printed text, is readed correctly, extracted correctly by Ocrad.js library. Handwriting
doesn’t really work, but maybe it’s just my handwriting which is awful. Yeah, and that’s
it. I will try to make this project available as soon I will be happy with it.
It’s currently in the, as you can see, early stage of development. Anyway, thanks for watching!
