Week 6 Vision Perception ! In general we (as humans) perceive a large number of inputs ! visual, auditory, smell, touch, taste, ESP ;-) ! Somehow we make sense of it all and do the right thing ! Perception is the action of taking raw inputs and producing some beliefs about the world Vision as perception ! We can think of our percepts as arising from some view of the world W P = g(W) ! If g is “graphics”, perhaps we can do vision as inverse graphics? W=g -1 (P) ? ! Problem: Many worlds are possible Vision as perception ! We can think of our percepts as arising from some view of the world W P = g(W) ! If g is “graphics”, perhaps we can do vision as inverse graphics? W=g -1 (P) ? ! Problem: Many worlds are possible Vision as perception ! We can think of our percepts as arising from some view of the world W P = g(W) ! If g is “graphics”, perhaps we can do vision as inverse graphics? W=g -1 (P) ? ! Problem: Many worlds are possible Vision as Bayesian Inference ! Can just treat this as an inference problem ! P(W|S) = ! P(S|W) P(W) ! The only problem then is trying to figure out priors over world states ! This can be tricky
