Image Fusion Based on NSCT

A ready-to-run remote sensing image fusion program based on Non-Subsampled Contourlet Transform (NSCT). This advanced transform, evolved from the Contourlet transform, features multi-scale and multi-directional decomposition capabilities while employing a non-subsampling approach that eliminates shift variance between subband images. The implementation involves image decomposition through NSCT, application of appropriate fusion rules, and final reconstruction via inverse NSCT transformation to produce fused images.
