Image copy/paste APR 23 2014
Project Naptha is a browser extension that lets you copy text from images on the web.
Project Naptha automatically applies state-of-the-art computer vision algorithms on every image you see while browsing the web. The result is a seamless and intuitive experience, where you can highlight as well as copy and paste and even edit and translate the text formerly trapped within an image.
I was skeptical of this actually working, but it totally does...try it on xkcd or Frank Sinatra's "loosen up" letter to George Michael for example. The translation and editing features aren't enabled yet, but the project's creator is working on them. (via @tcarmody)
