In some recent modeling work:
Laurent Perrinet, Guillaume S. Masson. Motion-based prediction is sufficient to solve the aperture problem. Neural Computation, 24(10):2726--50, 2012 http://invibe.net/LaurentPerrinet/Publications/Perrinet12pred
we study the role of transport in modifying our perception of motion. Here, we test what happens when we change the amount of noise in the stimulus.
In this script the predictive coding is done using the
MotionParticles package and for a http://motionclouds.invibe.net/ within a disk aperture.
