摘　　要：针对彩色图像签名问题进行了研究,基于哺乳动物视皮层神经元工作原理,提出了一种三通道脉冲发放皮层模型TSCM(Triple-Channel Spiking Cortical Model),实现了对彩色图像不变性特征的有效提取。TSCM模型不但具有常规脉冲耦合神经网络签名算法的平移、旋转、缩放不变性,而且算法更加简洁高效,对于噪声影响具有更强的鲁棒性。实验仿真结果验证了该算法的有效性。After studying the color image signature problem, a triple-channel spiking cortical model（TSCM）was proposed based on the working principle of mammalian visual cortex neuron model. The invariant characteristics of color image can be extracted effectively by TSCM. On the one hand, TSCM has the properties of ordinary pulse coupled neural network, such as invariances of translation, rotation, and scale. On the other hand,TSCM has more robust characteristics when it faces with the noise. At the same time, the algorithm is more compact and efficient. In the end, the effectiveness of TSCM was proved by the results of experiment and simulation.
