A Two-Stage Pansharpening Method for the Fusion of Remote-Sensing Images
The pansharpening (PS) of remote-sensing images aims to fuse a high-resolution panchromatic here image with several low-resolution multispectral images for obtaining a high-resolution multispectral image.In this work, a two-stage PS model is proposed by integrating the ideas of component replacement and the variational method.The global sparse grad
