Change detection is one of the most important applications in the remote sensing society. In change detection, pan sharpening fusion plays an important role to create a high-resolution dataset. A pansharpening method for enhancing satellite imagery is used as building a relatively high accuracy and low cost approach for image-based analyses. In this work, Pan sharpening Gram Schmidt technique is applied for enhancing certain features which are not visible in either of the single data alone. To perform the fusion, a low spatial resolution multi-spectral image of MODIS is fused with higher...
