Not seeing a whole lot of discussion about the implementation. Looking through the extension's code (which should be somewhere under your Chrome app files, if not online), briefly, it seems like an unsung hero here is Tesseract.js: http://tesseract.projectnaptha.com/ http://tesseract.projectnaptha.com/. The extension itself seems to do OCR (using Tesseract) on images and look for the string "adchoices", or else the adchoices icon, which yes, is cool: but just want to clarify that the folks at Tesseract seem to be doing the meaty "computer vision" part. EDIT: oh, this isn't markdown.
