| 摘 要： | 提出了一种基于非下采样Contourlet变换和脉冲耦合神经网络的无监督的不同时相的卫星影像的变化检测新算法。该算法将非下采样Contourlet变换和脉冲耦合神经网络这两种方法结合，将它应用于不同时相的卫星影像的变化检测。实验结果表明，与传统方法相比，对于高斯和斑点噪声，该算法具有更高的抗噪性能和检测精确度。

| Abstract: | An unsupervised change detection algorithm in multi-temporal satellite images based on nonsubsampled Contourlet transform and pulse coupled neural network is proposed.This method makes a combination of both nonsubsampled Contourlet transform and pulse coupled neural network,and applies it to change detection initially.Experimental results demonstrate that the proposed method has a higher stability and accuracy against Gaussian and speckle noise compared with traditional algorithms. |

| Keywords: | Nonsubsampled Contourlet Transform(NSCT) Pulse Coupled Neural Network(PCNN) unsupervised change detection multi-temporal satellite images remote sensing |
