چکیده انگلیسی
The fusion technique is a simple and fast but useful tool for integrated interpretation of various types of geophysical data. Based on the routine 2-D wavelet-based image fusion approach, we presented a 3-D wavelet-based fusion approach for comprehensively analyzing various physical-property voxel models inverted from gravity and magnetic data. The approach decomposes the models via the 3-D discrete wavelet transformation, and then fuses them according to the separated fusion rules of the approximated and detailed components in the wavelet domain, and then reconstructs the fused model via the inverse 3-D discrete wavelet transformation. The related parameters of the approach include the wavelet basis, the layer number of decomposition, the weighted coefficients for fusing the approximated components, and the window size for fusing the detailed components. Tests on the synthetic data and the real data from a metallic deposit area in Northwest China verified feasibility of the 3-D fusion approach.
