Fast Fusion of Multi-Band Images Based on Solving a Sylvester Equation
This paper proposes a fast multi-band image fusion algorithm, which combines a high-spatial low-spectral resolution image and a low-spatial high-spectral resolution image.The well admitted forward model is explored to form the likelihoods of the observations.Maximizing the likelihoods leads to solving a Sylvester equation.By exploiting the properties of the circulant and …
