Quotes by David Marr
The visual system is a highly specialized system.
The brain is a learning machine.
The computational approach provides a rigorous foundation for neuroscience.
The visual system is a highly parallel and distributed system.
The brain is a predictive machine.
The computational theory helps to bridge the gap between psychology and neuroscience.
The visual system is a highly adaptable system.
The brain is a creative machine.
The computational approach offers a new perspective on the brain.
The visual system is a highly complex system, but it is understandable.
The brain is a magnificent machine.
To understand vision by studying only neurons is like trying to understand a newspaper by studying its ink and paper.
The computational level is concerned with what is computed and why.
The purpose of vision is to recover the three-dimensional structure of the world from the two-dimensional retinal image.
Any particular cognitive function can be analyzed at three distinct levels of description.
The algorithmic level specifies how the function is computed.
The implementational level is concerned with how the algorithm is physically realized.
Vision is not a passive process but an active inference about the environment.
We must reverse-engineer the visual system to understand its principles.
The brain is a computational device, and cognition is computation.
