| Abstract: | In light of the shortage of single-wavelet in image transform,research subject has been progressed to multi-wavelet field.An improved algorithm of region energy image fusion with directional weighting along the edge information is proposed,which reconstructs wavelet coefficients corresponding to fused images,and then reconstructs fused images through inverse transform.In addition,cross-entropy,average error,peak signal to noise ratio and other parameters are used to evaluate and analyze the fusing property ... |
