摘要：Remote sensing images fusion can not only improve the spatial resolution for the original multispectral image, but also preserve the spectral information to a certain degree. In order to find out the fusion algorithm which is suited for QuickBird images fusion, four simple fusion algorithms, Multiplication (MLT), Modified Brovey (MB), High-Pass Filter (HPF) and the Smoothing Filter-based Intensity Modulation (SFIM) algorithm have been employed for result evaluation. The study is based on a QuickBird sub-scene covering different land use. Numerical statistical methods such as Bias of Mean, Correlation Coefficient, Entropy, Standard Deviation and Average Grads are used to quantitatively assess the fused images produced using the above algorithms. The analysis indicates that the SFIM-fused image has the best definition as well as spectral fidelity, and is the best in high textural information absorption. Therefore it is suited for QuickBird image fusion best
