Performance analysis of hierarchical fusion approaches for CCD/IR images

Hierarchical image fusion approaches for CCD/IR images are studied and the performance analysis of these fusion approaches is completed in this paper. The Hierarchical fusion methods include FSD pyramid, Laplacian pyramid, ration pyramid, contrast pyramid, gradient pyramid, morphological pyramid and discrete wavelet transform. The performance measures of evaluating fusion images deal with standard deviation, entropy, cross entropy and spatial frequency. Experimental results show that morphology pyramid method is more suitable for CCD/IR image fusion than other ones proposed in this paper.
