A perceptual system is a computational system (biological or artificial) designed to make inferences about properties of a physical environment based on scenes.
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: 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,[1][2] and computer science.
