A new computer vision system inspired by cats' eyes could enable robots to see the world around them more accurately than ever before.
They chose a cat's eye for inspiration because our furry friends have great vision in both light and dark environments. During the day, a cat's pupil is a vertical slit-like shape that filters out light and reduces glare, helping a cat to focus. The pupil then widens to let in more light at night — with a reflective layer called the tapetum lucidum enhancing their vision by reflecting visible light back through the retina and increasing the light available to photoreceptors.
"Robotic cameras often struggle to spot objects in busy or camouflaged backgrounds, especially when lighting conditions change. Our design solves this by letting robots blur out unnecessary details and focus on important objects," study lead author Young Min Song, professor of electronic engineering at Gwangju Institute of Science and Technology in South Korea, said in a statement.
