Image pansharpening: Comparison of methods based on multiresolution analysis and component substitution

In this paper, we propose to compare pansharpening techniques based on multiresolution analysis (MRA) and component substitution (CS). The appropriate way is to show the difference on methods which are identical in how to incorporate spatial details into multispectral (MS) data. Our study relies on the Gram-Schmidt (GS) transform technique that is an… CONTINUE READING
