Examples
- Afterwards , in order to decrease the contradiction between the more complex and mass remote sensing image data and relatively slow speed of information extraction , an improved sfim image fusion method is proposed . this modified algorithm is on the base of sfim fusion technique , combines ihs method and sfim method and then replaces the former mean filter by an adaptive weighted mean filter . compared with the results of several common fusion techniques through a set of simulation tests between multispectral images and panchromatic images , it is proved that the new method can get an excellent result for the aim of improving spatial resolution while preserving the spectral information of multispectral images
论文的主要工作和成果包括:在像素层,论文研究了多传感器数据融合理论及遥感图像预处理的过程和步骤,归纳了多源遥感图像像素层融合的常用算法,并针对目前遥感数据呈海量化、复杂化这一发展趋势同遥感信息提取的能力和效率滞后这一矛盾,在sfim算法的基础上,将ihs变换与sfim相结合,将原算法中的均值滤波器改进为自适应加权均值滤波器,提出了一种改进的sfim算法,通过对一组多光谱图像和全色图像的双传感器融合仿真对比试验,证明了该算法在保持原多光谱图像光谱信息的同时,能够有效提高融合图像的空间分辨能力。
