A perceptual system has been defined as a computational system (biological or 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 information that can flow from a physical environment into the computer via sensory transduction. By definition, a sensory organ is required to provide scene input.
Examples of perceptual systems include:
- The human visual system
- The human auditory system
- A bat's sonar/echolocation system
- A man-made light intensity 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[1][2], and computer science.
