 The GIHS-TV framework is a novel approach to pan-sharpening which combines the advantages of the GIHS scheme and the L1-TV constraint to achieve better spectral distortion reduction. It also provides faster computation than other methods. Experimental results show that this method can produce high quality images with fewer artifacts compared to other methods.

The GIHS-TV framework is a novel approach to pan-sharpening which combines the advantages of the GIHS-TV framework and the L1-TV constraint to achieve better spectral distortion reduction. It also provides faster computation than other methods. It also provides more visual distortion.
