More quotes by David Marr

Vision is the process of discovering from images what is present in the world, and where it is.

The primitives of a representation are the most elementary units of shape information available in a representation.

The abstract properties of this mapping are defined precisely, and its appropriateness and adequacy for the task at hand are demonstrated.

Vision is a process that produces from images of the external world a description that is useful to the viewer and not cluttered with irrelevant information.

Steven Yantis (2001)

In order to understand bird flight, we have to understand aerodynamics; only then does the structure of feathers and the different shapes of bird's wings make sense.
