摘要：
This paper presents a simple yet efficient algorithm for multifocus image fusion, using a multiresolution signal decomposition scheme. The decomposition scheme is based on a nonlinear wavelet constructed with morphological operations. The analysis operators are constructed by morphological dilation combined with quadratic downsampling and the synthesis operators are constructed by morphological erosion combined with quadratic upsampling. A performance measure based on image gradients is used to evaluate the results. The proposed scheme has some interesting computational advantages as well. (C) 2005 Elsevier B.V. All rights reserved.
