The
long-term goal of our research is an understanding of the neuronal computations
that support the brain’s remarkable ability to recognize visual
objects. The key computational challenge of object recognition is the
extraction of object identity irrespective of visual clutter, object position,
size, pose and illumination.
Our working hypothesis is that a series of
brain processing stages rapidly transform pixel-based images of the
world into patterns of neuronal activity that emphasize object identity
and discount object position, size, view, and illumination. Understanding these transformations and the resulting high level neuronal object representations is arguably the most important unsolved problem in sensory systems neuroscience. Such an understanding will provide deep insight into the neuronal mechanisms that underlie memory
and cognition, will enable the creation of artificial vision systems and
visual prostheses, and will assist in the development of molecular and
behavioral techniques to aid those suffering from learning and memory
disabilities.
