| 摘 要： | 脉冲耦合神经网络（PCNN）比传统神经网络更好地模仿了生物神经元,既考虑空间累加,又考虑了时间累加。在此用加性耦合代替乘性耦合,在图像处理效果上与耦合和无耦合PCNN的效果相比,其差别较小,熵与耦合PCNN处理后图像的熵基本一致。但加性耦合连接的PCNN,改变了无耦合PCNN的周期特性,提供了停止条件,保持了PCNN的旋转不变性、缩放不变性等一些特性,同时保持了时间和空间上的积累,且迭代次数少,计算量相对较小,更适合于硬件实现。

| Abstract: | The pulse coupled neural network(PCNN) is better than the traditional neural network.It can imitate biological neurons with considering space and time accumulation.When plus-coupled is proposed instead of multiplicative-coupled in PCNN,the difference of image processing effect is tiny.The entropy of plus-coupled is approximate compared with that of coupled and non-coupled PCNN,but PCNN with the plus-coupled connection overcomes the periodicity of non-coupled PCNN,provides the stop conditions,and maintains r... |
