摘要：
A new pan-sharpening method based multispectral (MS) image intensity modulation is proposed. Firstly, according to the spectral correlation between MS image and panchromatic (PAN) image, a new spectral-enhanced PAN (SPAN) image is obtained. Then, SPAN image is utilized to calculate the spectral and spatial difference coefficients. Finally, the fused high resolution MS (HRMS) image is generated by modulating the intensity of the upsampled MS image. The experimental results demonstrate that the proposed method performs well both on spatial details preservation and spectral distortion reduction.
