“Call it advertisement hacking. Technology-inspired artists have designed ways for you to mask or perhaps even delete company logos in your field of view as you wander around a city or shopping centre.The trend subverts a technology called augmented reality ARMovie Camera, by which virtual information – say restaurant ratings – is overlain on the real world as you peer through smart glasses or a smartphone camera.New York artist Jeff Crouse has designed a program called Unlogo, which detects corporate logos in a video stream, then replaces them. The software uses a computer-vision system, normally used in robotics, to learn to recognise logos at different angles and in varied lighting. His current prototype overlays a logo with a photo of that company’s CEO.The project is still under development and does not yet run in real time, but Crouse’s goal is to produce a video filter for removing logos from, say, home movies.” (via New Scientist)
