Cat flaps are useful little things, especially if you don’t want your cat to be entering the house from the window sill. Now the smart folks over at Quantum Picture have come up with a system that can unlock the cat flap based on image recognition. This system actually uses a camera to capture the profile of anything that approaches the cat door, comparing it with the image that’s stored in the positive identical identification sets. So with this in place, you won’t have to worry about the skunk walking into your house via the cat flap anymore. You can find the full details of this project at Quantum Picture.
