- "Analog VLSI for Machine Vision"
-
-
- Analog VLSI has the potential for fast, small, low power, cheap front end
- vision processing that does not require a great deal of support circuitry.
- But it is hard to compete head on with digital VLSI, which has a much longer
- development history. So merely implementing existing algorithms --- which
- were developed in the context of sequential digital machines --- is not a
- good idea. One needs to find ways to exploit the medium. What are analog
- networks good at computing? Several devices have been built that exploit
- properties of resistive sheets, theorems for converting area integrals into
- contour integrals, properties of Gaussian integers, switched capacitor
- networks and so on. Possibly the most promising area is in real-time
- feed-back involving motion vision, where the long latency of competing
- pipelined digital systems is deadly.
