A Survey of neuromorphic vision system: --Biological nervous systems realized on silicon

Neuromorphic systems emulate the functionality of neural principles found in biology, especially in the brain structures of retina and cochlea. The paper focuses on the introduction of neuromophic vision systems. A brief history of neuromorphic systems and neuromorphic vision chips is presented, the advantages and disadvantages of neuromorphic vision systems are highlighted, and some research states towards realizing the systems are discussed in this paper. Finally the development trends of neuromophic vision systems are summarized. It is shown that the neuromophic vision systems have promising improvement prospects.
