This paper proposes a nonlinear oscillator network model for gray-level image segmentation suitable for massively parallel VLSI implementation. The model performs image segmentation in parallel using nonlinear analog dynamics. Because of the limited calculation precision in VLSI implementation, it is important to estimate the calculation precision required for proper operation. By numerical simulation, the necessary precision is estimated to be 5 bits. We propose a nonlinear oscillator network circuit using the pulse modulation approach suitable for an analog-digital merged circuit architecture. The basic operations of the nonlinear oscillator circuit and the connection weight circuit are confirmed by SPICE circuit simulation. The circuit simulation results also demonstrate that image segmentation can be performed within the order of 100 µs.
