Image Segmentation/Extraction Using Nonlinear Cellular Networks and Their VLSI Implementation Using Pulse-Modulation Techniques

摘要

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 10×10-pixel Image segmentation and extraction are demonstrated by high- Speed circuit simulation.
