| 摘 要： | 提出一种基于非下采样contourlet变换(NSCT)与脉冲耦合神经网络(PCNN)的图像融合算法.该方法首先利用非下采样eontourlet变换对输入图像进行多尺度分解、多方向稀疏分解,准确捕获图像中的高维奇异信息,然后利用脉冲耦合神经网络的同步激发特性确定融合规则,选取融合系数,提高融合性能.实验结果表明,算法比小波变换、contourlet变换有更好的融合性能.

| Abstract: | A fusion algorithm based on Nonsubsampled Contourlet Transform(NSCT)and Pulse Coupled Neural Network(PCNN)was proposed.By using NSCT,the input images were decomposed into a number of sub-images with various scales and directional features.Then,based on PCNN,a fusion rule was given.The fused coefficients could be generated by PCNN-based fusion rule and the fused image was obtained by performing the inverse NSCT to fused coefficients.The experimental results show that the fusion method is more effective than ... |
