| 摘 要： | 采用BP神经网络与SVR融合法相结合的方法来实现像素级多源图像融合。改进型的SVR方法,用来进行全色波段和多光谱波段的融合。首先将各多光谱波段与全色波段求算回归系数,然后利用回归系数与多光谱波段合成模拟高空间分辨率全色波段,最后利用比值变换完成各波段的融合。通过仿真证明,BPNN-SVR融合法优于SVR融合法。

| Abstract: | The method which unified the BP neural network and the SVR fusion law to realize the pixel-leve l multiple source image fusion is used in this paper.The advanced version SVR method was used to carry on the panchromatic wave band and the multi-spectrum wave band fusion.First asks each multi-spectrum wave band and the panchromatic wave band to calculate the regression coefficient,then simulates the high spatial resolution panchromatic wave band using the regression coefficient with the multi-spectrum wave band synthesis,finally completes various wave bands using the ratio transformation the fusion.Proved through the simulation that,the BPNN-SVR fusion method surpasses the SVR fusion method. |
