Why is Perceptual Organization important? 
Organized form is a good indicator of an underlying causal agent. 
P(Causality\Or ganization) = 
P(Or g anization\Cau sal it y)P (Causality) 
P(Organization) 
P{Causality) captures the meaningfulness of a scene. 
P(Organization\Causality) is the probability that we will ob 
serve an organization among a set of features given that they 
come from the same cause. This captures the fact that matter is 
coherent. 
P(Organization) is the prior probability of organization being 
present in a set of features. 
A good organization: low P(Organization) and 
high P(Organization\Causcility).
