文摘内容
Several image fusion approaches for CCD/SAR images are studied and the performance evaluation of these fusion approaches is completed in this paper,Fistly,the preprocessing of CCD/SAR images before fusion is fulfilled,Then,the imager fusion methods including linear superposition,nonlinear operator method and multiresolution methods,of which the multiresolution methods include Laplacian pyramid ,ratio pyramied,contrast pyramid,gradient pyramid,morphological pyramid and discrete wavelet transform,are adopted to fuse two types of images ,Lastly,the four performance measures,standard deviation,entropy,cross entropy and spatial frequency,are calculated to compare the fusion results by different fusion approaches in this paper,Experimenteal results show that contrast pyramid,morphology pyramid and discrete wavelet transformation in multiresolution approaches are more suitalbe for CCD/SAR image fusion than other ones proposed in this paper and the objective preformance evaluations of CCD/SAR image fusion approaches are effective。
