Perception System

The perception system relies on a set of on-board virtual sensors to provide sensory information about the dynamic environment, including eyes that can produce time-varying retinal images of the environment. The brain's perception control center includes a perceptual attention mechanism which allows the artificial fish to train its sensors at the world in a task-specific way, hence filtering out sensory information superfluous to its current behavioral needs. For example, the artificial fish attends to sensory information about nearby food sources when foraging.
