Abstract from 2012 paper Multiscale image fusion using an adaptive similarity-based sensor weighting scheme and human visual system-inspired contrast measure
SUMMARYTufts researchers have developed a novel image fusion algorithm with superior performance PROBLEMThe goal of image fusion is to combine multiple source images obtained using different capture techniques into a single image to provide an effective contextual enhancement of a scene for human or machine perception. In practice, considerable value...
