How do cameras detect faces? In most cases, the face detection system will confirm detection by overlaying a rectangle on each face in the scene displayed on the camera’s LCD. Some systems use a different colour to identify the face that will be used as a focusing target. Tracking facilities are also provided by some […]

How is earth magnetic field similar to a bar magnet?
How is earth magnetic field similar to a bar magnet? Earth is similar to a giant bar magnet with magnetic field lines radiating from the south to the north magnetic pole.
