Fusion of Multispectral and Panchromatic Images Using Fuzzy Integral Based on Fast Intensity-Hue-Saturation Transform

To fuse multispectral images and panchromatic images, this paper proposes a new fused method using fuzzy integral based on fast intensity-hue-saturation (IHS) transform. The proposed method enables fast, easy implementation. We choose the fuzzy density according to the importance of the spectral and spatial resolution in the fused images respectively. With an appropriate fuzzy density, the new approach can update the spatial detail quality of the fused image while minimizing the spectral distortion relative to the original low-resolution multispectral images. The experiment results carried out on Landsat-7 ETM+ mutlispectral and panchromatic image show the proposed approach effective.
