This paper proposes a new method for image segmentation and extraction using nonlinear cellular networks. Flexible segmentation of complicated natural scene images is achieved by using resistive-fuse networks, and each segmented regions is extracted by nonlinear oscillator networks. We also propose a nonlinear cellular network circuit implementing both resistive-fuse and oscillator dynamics by using pulse-modulation techniques. The basic operation of the nonlinear network circuit is confirmed by SPICE simulation. Moreover, the 1010-pixel image segmentation and extraction are demonstrated by high-speed circuit simulation.
