It is widely believed that visual systems
are optimized for the visual properties of the environment inhabited
by the host organism. A specific instance of this principle known as
the Efficient Coding Hypothesis holds that the purpose of early
visual processing is to produce an efficient representation of the
incoming visual signal. The theory provides a quantitative link
between the statistical properties of the world and the structure of
the visual system. As such, specific instances of this theory have
been tested experimentally, and have be used to motivate and constrain
models for early visual processing.
