While at NDC is Oslo, Carl and Richard talk to Martin Jul about the state of visual computing technology today. As Martin says, the future is very bright - amazing free libraries are now available that make it simple to do image and character recognition with all sorts of cameras, even one on the Raspberry PI! The conversation digs into a project that Martin built to identify when the pizza guy is at his front door, exploring what it takes to recognize a pizza box in video. There are digital cameras everywhere today, shouldn't we be building apps to take advantage of them?
