Abstract
Among the methods of spatial detail injection, smoothing-filter-based intensity modulation (SFIM) can quickly merge a huge amount of different spatial resolution imagery with little color distortion. However, the success of spatial-detail injection mainly relies on the designed low-pass filter. For IKONOS-QuickBird image fusion, SFIM requires an elaborate filter to extract adequate spatial details. To ease the filter design and preserve complete spatial information, a modified approach is presented. Experimental results demonstrate that the proposed technique provides significant improvements over the original method.
