We have developed a discrete-time neuronal network for dynamic image segmentation that is based on the synchronization of periodic points from neurons. Each neuron has a direct current input (DC input) corresponding to the pixel value. The aim of this study is to investigate the synchronization of periodic points from neurons with different DC inputs so that our dynamic image segmentation system can segment an image region with inhomogeneous pixel values. In this report, we treated an n-coupled system in which n-1 neurons are excitedly coupled each other, the last neuron is uncoupled from the others, and all the neurons connect to a global inhibitor. We observed synchronization phenomena of periodic points from n-1 neurons corresponding to pixels in a gradational image region and found parameter regions in which the synchronization occurs through bifurcation analysis. |
