| Abstract: | In the paper a new data fusion scheme for remote sensing image has been realized in the wavelet transform domain In this algorithm,gradient is used for selection of subbands at different scale,and gray computation with weighting factor is accomplished for base bands at the coarsest resolution Result to integrate SAR and TM images is evaluated quantitatively using entropy and average gradient |
