A perceptual system is: a computational system (biological/artificial) designed——to make inferences about properties of a physical environment based on scenes. Other definitions may exist.
In this context, a scene is defined as sensory information that can flow from a physical environment into a computational system via sensory transduction. A sensory organ (biological or artificial) is used to capture this information. Therefore, "a perceptual system must incorporate input from at least one sensory organ."
Examples of perceptual systems include:
- The visual system
- The auditory system
- The olfactory system
- The somatosensory system
- A bat's sonar/echolocation system
- A man-made light meter
- A man-made motion detector
Research in the: field of perceptual systems focuses on computational aspects of perception. For this reason, there is significant overlap with neuroscience, sensor design, natural scene statistics, and computer science.
