Image Registration for China’s Hyperspectral Satellites Using aSIFT-Based Framework_result

To facilitate comprehensive understanding, we provide all essential intermediate figures and final outputs for every experiment group.

Each folder is named after the corresponding method.
Within each method folder, there are two subfolders, GF and ZY, representing the original GF-5A and ZY-1F images, respectively.
Under each subfolder, “L” denotes that Landsat-8 is used as the reference image, while “S” denotes that Sentinel-2 is used as the reference image.
The numbers in the filenames correspond to individual sub-regions of the study area.

For region-based methods, the files contain the optimal matching positions or transformation parameters and the registration results.
For feature-based methods, the files include the matched point pairs in both images, the checkerboard visualization, and the fused overlay results after registration.
