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
論文的主要工作和成果包括：在像素層，論文研究了多傳感器數據融合理論及遙感圖像預處理的過程和步驟，歸納了多源遙感圖像像素層融合的常用演算法，並針對目前遙感數據呈海量化、復雜化這一發展趨勢同遙感信息提取的能力和效率滯后這一矛盾，在sfim演算法的基礎上，將ihs變換與sfim相結合，將原演算法中的均值濾波器改進為自適應加權均值濾波器，提出了一種改進的sfim演算法，通過對一組多光譜圖像和全色圖像的雙傳感器融合模擬對比試驗，證明了該演算法在保持原多光譜圖像光譜信息的同時，能夠有效提高融合圖像的空間分辨能力。 -
