Visual perception

Visual perception is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment. When an object is moving we tend to see if it moving from left to right or right to left. A good example of visual perception would be bistable image. Bistable image is when an image can be interpreted in one or two different possible ways. Another great example that tends to trick our vision is the hollow face illusion. The hollow face illusion is an optical illusion in which the perception of a concave mask of a face as a normal convex face, which appears to follow you as you move past it.
