| 摘 要： | 采用拉普拉斯、对比度、梯度以及形态学4种金字塔分解算法,以区域特征选择为融合规则对IKONOS多光谱和全色波段影像进行融合,从空间信息和光谱特征两个方面对融合结果进行对比分析,探讨各种算法的遥感影像融合效果。实验结果表明:基于形态学金字塔算法影像融合的空间信息增强和光谱特征保留效果最好;Laplacian算法次之;对比度和梯度算法效果最差。

| Abstract: | Taking regional-features' selection as the fusion rules,the multi-spectral and panchromatic of IKONOS images are fused separately by Laplacian,Contrast,Gradient and Morphological Pyramid Algorithms.Then the fusion effects based on these four algorithms are analyzed comparatively from two aspects of spatial information and spectral features.The results show that:Image fusion based on morphological pyramid algorithm has the best effect in enhancing the spatial information and retaining the spectral characteri... |
