A fast and effective image fusion method is proposed
for creating a highly informative fused image through merging
multiple images. The proposed method is based on a two-scale
decomposition of an image into a base layer containing large
scale variations in intensity(and a detail layer capturing small scale details. A novel guided filtering-based weighted average technique is proposed to make full use of spatial consistency
for fusion of the base and detail layers. Experimental results
demonstrate that the proposed method can obtain state-of-the-art
performance for fusion of multispectral, multifocus, multimodal,
and multiexposure images.)
