Perceptual system
A perceptual system is a computer (biological or artificial) designed to make inferences about properties of a physical environment based on scenes.[1] In this context, a scene is defined as information that can flow from a physical environment into the computer via sensory transduction.
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 concentrates on the computational aspects of perception. For this reason, there is significant overlap with neuroscience, sensor design, natural scene statistics[2][3], and computer science.
