CMOS dynamic linking networks for real-time human face tracking

Dynamic linking networks are very effective in locating human faces, as they are invariant to changes in position, orientation, scale, deformation, and partial lighting. Additionally, these networks are well suited for analog VLSI using very simple CMOS circuits such as programmable ring oscillators, strongly coupled diffusion lattices, and AC-coupled Hebbian synapses. Dynamic linking networks are orders of magnitude faster than digital computers, thus they provide a fast, efficient, and robust means of tracking faces in real-time. Transistor-level simulation results are presented for the .5 μm TSMC CMOS technology with 3-volt supply
