Underwater computer vision is like the eyes of a computer that can see things underwater. It is like when we wear goggles when we swim, but instead of seeing with our own eyes, it uses a special camera that can see underwater.
This special camera takes pictures or videos of what is happening underwater and sends them to a computer. The computer then uses special software to interpret what is in the pictures or videos. The software can recognize different things like fish, plants, rocks, and even ships or submarines.
This is helpful because sometimes scientists, explorers, and engineers need to know what is happening underwater but they cannot go there themselves. The underwater computer vision can help them explore and understand the underwater world without needing to be there in person. It's like having underwater superhero eyes!
