Perceptual system
A perceptual system is a computer 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.
Perceptual systems can be biological or artificial. By definition, a perceptual system must receive input from sensory organs.
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[2][3], and computer science.
