Fusion of Remote Sensing Images Based on Morphological Pyramid and Its Performance Evaluation

A fusion method is introduced which is based on morphological pyramid decomposition,and applied to ikonos images.As a non-linear filter,the morphological filter outperforms the linear filter(eg.Gaussian filter) in precise edge localization,and better represents the detailed spatial information of images.Results and analysis of the experiments show that the fusion method based on morphological pyramid is better than the methods steming from Laplacian pyramid or contrast pyramid.
