A lot of the challenges in making driverless cars has been in visual object recognition, which is probably the "visual post-processing" you mean.
It is important to note that humans, and other mammals, are very hard-wired to process vision and other inputs. For example, the retina is more than just an organic lens; it also encodes information about the motion of objects seen within its field of vision:
So in addition to post-processing, there is probably significant pre-processing done by the sensory extensions of our brain. Similarly, the physicist Georg Zweig studied the cochlea and found how it mechanically separates sound into its frequency distribution. Zweig's research on the cochlea also resulted in the discovery of the continuous wavelet transform, whose discrete version may be familiar through its use in JPEG2000.
