Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0035] Such as figure 1 As shown, a Shearlet domain multispectral and panchromatic image fusion method based on spectral characteristics includes the following steps:
[0036] (1) Perform IHS transformation on the multispectral image to obtain the brightness component P I , chrominance component P S , saturation component P H , the brightness component P of the multispectral image I Through the two-dimensional empirical mode decomposition BEMD, n-1 two-dimensional intrinsic modulus functions BIMF with frequencies from high to low are obtained t , t=1,2,...n-1, n>3 and margin res;
[0037] (2) Calculate n-1 two-dimensional intrinsic modulus function BIMF t The energy and sorting, the sum of the first three components of the statistical energy sorting B MS , the BMS and panchromatic image I PAN Perform the three-layer decomposition of the Shearlet trans...
