Abstract:
As we move about the world, the image of objects on
our retina undergoes affine transformations. In order to simplify cortical
computations, the symmetries of this transformation - translation, rotation,
and magnification - must be preserved in the cortical operation. I will examine
the consequences of the cortical representation of the affine symmetries and
explain, through a review of how primary visual cortex encodes the visual world,
the computational significance of these symmetries.
