本文提出了一种新的解剖图像和功能图像的融合算法,选取了局部拉普拉斯滤波(local Laplacianfiltering, LLF)作为融合过程的分解工具,该工具在增强细节的同时保护边缘,保证解剖图像的细节信息不被功能图像的颜色信息遮盖. |
A new fusion algorithm for anatomical andfunctional images is proposed in this paper. Local Laplacian filtering (LLF) is chosen as the decompositiontool in the fusion process, which can enhance the details, protect the edges, and ensure that the details of theanatomical features in the fused images cannot be covered by the color information of the functional images. |

对于细节图,采用参数自适应的简化脉冲耦合神经网络(parameteradaptive simplified pulse coupled-neural network, PA-SPCNN)模型进行细节图融合,选取改进的拉普拉斯和(novel sum-modified-Laplacian, NSML)与彩色显著特征信息(color saliency feature, CSF)分别作为解剖图像和功能图像所对应的PA-SPCNN模型的外部刺激输入.最后,使用逆LLF变换获得融合图像. |
For detailed images, the parameter-adaptivesimplified-pulse-coupled neural-network (PA-SPCNN) model is used to fuse the detailed images. The novel sum?modified-Laplacian and color-saliency feature are selected as external-stimulus inputs of the PA-SPCNN modelin the anatomical and functional images, respectively. Finally, the fusion image is obtained by an inverse-LLFtransform. |
