Visual homing is the ability to return to a goal by comparing an image captured at the goal to the current image. It is believed to be a fundamental mechanism in the navigational capabilities of insects such as bees and ants. It is also useful for robotics as a means of moving between familiar places. Biologically plausible visual homing was the subject of Dr. Andrew Vardy’s Ph.D thesis.
