There was this idea floating around on some virtual reality forums some years back about an "adblock for real life" that would work in a very similar way with a head-mounted display. In terms of pattern recognition it is not at all difficult. Detection and tracking of a set of images is pretty much a solved problem in computer vision (doing it reliably in realtime is still somewhat of a black art). I like how this is framed as an art project, and it's a very cool proof of concept, though it's an issue that it doesn't black out logos until after they have been seen, and the blackout box blinking on and off as the detector passes its threshold only draws attention to those areas. A practical implementation could use inpainting algorithms (also built into OpenCV, and even provided in one of the samples) to fill the logoed areas with background-like texture, so that it's not an obvious "censored" black patch but a smooth transition.

see also the artvertiser, by julian oliver, damian stewart and more: http://selectparks.net/~julian/theartvertiser/ http://selectparks.net/~julian/theartvertiser/ which is an art project (along similar lines as unlogo) which replaces advertisements with art. nice to see both unlogo and artvetiser be open source, it will be interesting to see the different directions people can take these ideas.

  Yes -- Julian's project is great, and was definitely an inspiration to me. It is mentioned in the video: http://www.kickstarter.com/projects/816924031/unlogo-the-corporate-media-filter-0 http://www.kickstarter.com/projects/816924031/unlogo-the-cor...

I believe Limor Fried created some type of glasses that would detect refresh rates of video sources and black out the glasses when viewing the monitor/tv. No image recognition, though.

  If you could look through a (linear) polarizing filter oriented at 45 degrees from the vertical, you could kill off most of LCD displays. Unfortunately, sunglasses with polarizer are usually polarized at the wrong angle, so you have to tilt your head to see the effect (black screens).
