Neuromorphic VLSI systems for visual information processing: drawbacks

In this paper, the neuromorphic VLSI approach for visual processing and detection is presented. A brief history of neuromorphic vision systems is presented. The advantages and disadvantages of neuromorphic systems are highlighted and some of the major barriers towards realizing these systems are discussed. In particular, the implementation of early visual processing models using analogue VLSI is described and some of the general misconceptions are addressed.
