Pareidolia

Pareidolia is the perception of meaningful forms, especially faces, in ambiguous or random stimuli. It arises when perception organizes incomplete sensory information into a familiar pattern.

Face perception: Face perception is the visual and cognitive processing that identifies faces and their features. The brain’s specialized face-processing systems help make face-like patterns stand out.
Man in the Moon: The Man in the Moon is a human face or figure perceived in the Moon’s contrasting surface patterns. It is a longstanding example of face perception imposed on an inanimate surface.
Radiology: Radiology is the medical specialty that uses imaging to diagnose and treat disease. Ambiguous scans can invite false pattern recognition, making careful image interpretation essential.
Hallucination: A hallucination is a perception-like experience occurring without an external stimulus that could produce it. Pareidolia begins with an external stimulus, even when that stimulus is ambiguous.
Gestalt psychology: Gestalt psychology studies how perception organizes elements into structured wholes. Its principles describe how scattered features can cohere into a recognizable form.
Rorschach test: The Rorschach test is a psychological assessment using interpretations of symmetrical inkblots. Its ambiguous images invite observers to impose recognizable forms on uncertain patterns.
Computer vision: Computer vision is the field of computing that enables machines to interpret visual information. Face-like patterns test how image-recognition systems respond to ambiguous visual features.
Illusion: An illusion is a misleading or distorted perception of an actual stimulus. Pareidolia is one kind of illusion involving meaningful forms perceived in ambiguous input.
Predictive processing: Predictive processing is the theory that perception combines sensory input with predictions about its causes. Expectations can shape which interpretation wins when sensory evidence is incomplete.
Face on Mars: The Face on Mars is a mesa in the Cydonia region once photographed under lighting that suggested a face. Later, higher-resolution images showed how illumination and viewpoint can produce a face-like reading.
