| 摘 要： | 边缘是图像的重要特征。在应用细胞神经网络提取图像边缘时,网络的稳定性和参数的选择是关键。文中推导了细胞神经网络的稳定条件,并提出了网络参数的自适应设计思路。基于Matlab7.0平台,通过编写仿真程序,检测灰度图像边缘,得到良好效果。实验证明,该法还能有效抑制噪声的干扰。

| Abstract: | Edge is an important character of the image.The stability of the network and the parameter choice are the key problems when Cellular Neural Network(CNN) is used to pick up the image edge.The stable condition of CNN is discussed,and the self-adaptive template parameters of the network are fixed reasonably.Based on Matlab 7.0,the simulation applied to the edge detection has presented its validity in the image processing,as well as the noise control. |

| Keywords: | edge detection Cellular Neural Network(CNN) stability template parameters self-adaptive |
