Objective image fusion performance measure
...First, the base and detail layers of different source images are fused together by weighted averaging B = N∑ n=1 WBn Bn (17) D = N∑ n=1 WDn Dn. (18) Then, the fused image F is obtained by combining the fused base layer B and the fused detail layer D F = B + D. (19)...
