A pixel-level entropy-weighted image fusion algorithm based on bidimensional ensemble empirical mode decomposition by Pei Wang, Hui Fu, Ke Zhang

“…In this article, an adaptive image fusion algorithm based on the representation of bidimensional ensemble empirical mode decomposition is proposed. This novel algorithm decomposes the source image by the bidimensional ensemble empirical mode decomposition algorithm, and a pixel-level weighting fusion method is then presented based on the entropy of intrinsic mode function; the fusion image can thus be obtained by inversing bidimensional ensemble empirical mode decomposition on the composite representation. …”
