illusionary contours

Illusory contours are visual phenomena where our brain perceives edges or shapes that aren't physically present in an image. For example, when we see a series of dots arranged in a pattern, our mind fills in the gaps, creating the illusion of a complete object, like a triangle, even though no actual lines define it. This occurs because our brain uses visual cues and context to organize what we see, helping us interpret the world more effectively. Illusory contours demonstrate the complexity of visual perception and how our brain constructs reality based on incomplete information.
